Specifications are subject to change without notice.320 General Description Continual advances in digital IC technology are creating stringent demands on EMI/RFI levels in equipment. EMI/RFI low pass filters are required in personal computers, data terminals, test equipment and process con- trollers for high frequency suppression into or out of elec- tronic equipment. Filter Selection and Design Considerations The “roll-off” frequency fc, defined as the frequency at which the filter passes one-half the power it receives at its input terminal, can be specified from the low megahertz range up to about 100MHz. This frequency, also known as the “-3 dB” frequency, will be determined by the R and C values chosen. Custom resistor and capacitor values are available to optimize system performance. The specification of these values will depend on con- straints relating to noise frequencies, system performance and driver loading. The following procedure is suggested to choose appropriate values of R and C. The first step is to determine the desired roll-off frequency of the filter, which will lie between the signal frequency and the dominant frequencies of the EMI/RFI noise. By determining the pole of the filter (setting the denominator of the transfer function equal to zero), the roll-off frequency can be expressed in terms of R and C: fc = RS + RL + 2R pC(R + RS)(R + RL) Furthermore, the RC combination must be chosen so that the additional RC time delay will not result in exceeding the sampling window of the receiving IC, due to excessive lengthening of signal rise and fall times. Rise time from 10% to 90% of the waveform amplitude can be calculated in terms of the circuit’s RC time constant using the 1 –exp (–t/RC) relationship for a charging capacitor. At 10%, t L = 0.1 time constants, and at 90%, t H = 2.3 time constants. “Time constant” equals R thC, where R th is the Thevenin-equivalent resistance as seen by the capacitor. Therefore, equating the difference in the two times to the maximum tolerable rise (or fall) time: tmax = t H - tL = 2.2RthC tmax = 2.2 (R + RS)(R + RL)C RS + RL + 2R A final consideration is the insertion loss. As mentioned previously, the voltage drop across the two resistors will attenuate the voltage reaching the load. Normally, logic high and low levels will still be within valid limits. The signal attenuation can be minimized by choosing small R values rel- ative to the load impedance. Typical values for R range from 10 to 50 ohms. Bourns Low-pass Filters for EMI/RFI Suppression NO.

Bus termination (in this case, RC termination technique) considerably reduces overshoots and ringings. Transmission lines require termination when the time it takes the signal to travel from one end of the line to the other (the propagation delay) amounts to 1/2 or more of the edge rate of the signal (signal rise time or fall time). In other words, termina- tion is required when: Tpd > (1/2)Te Te = edge rate Tpd = propagation delay Present high-speed logic families have typical rise times of 2 nanoseconds, while the propagation delay of a common PCB is about 1.77 ns per foot. Applying the above relationship, a trans- mission line will require termination if it is longer than 7 inches. High performance systems will commonly need Bourns termi- nation networks for CPU address, data, and control lines. In addition, clock inputs, write and read strobe lines, chip select or output enable lines of high speed devices such as static RAMs, PROMs, and PLDs will also need termination networks. TERMINATION TYPICAL ADDS RESISTOR CAPACITOR TECHNIQUE POWER DELAY VALUE VALUE USAGE RC MEDIUM NO Zo 200-500pF General Description This series of RC Networks is designed to eliminate transmis- sion line effects, such as signal reflections and ringing which influence high speed CMOS. The Networks capacitor blocks DC currents while acting as a short circuit during signal transmi- tions, thus reducing power consumption. The capacitor also holds the bus at the last logic level to avoid excessive currents. Block Diagram Of CPU/BUS Configuration Bus Termination Applications Of Bourns Networks At high frequencies, the traces on a printed circuit board act as transmission lines—in which impedance mismatches can cause distortion of signals on that line. Terminating the lines with resistor or resistor-capacitor networks provides the means to match impedances and reduce signal distortion. RC Terminator Networks 700 Series

Specifications are subject to change without notice. 323 For designers developing high performance systems, exact termination resistances which account for line loading may be desirable. This resistance (or equivalent resistance) can be cal- culated using the formula: Rterm = Zo 1 + Cd / Co where Zo is the characteristic impedance of the line, Cd is the total capacitance associated with the receiving devices (typically 5 pF per input gate) or other loads off the line, and Co is the intrinsic capacitance of the line. The series termination technique suppresses reflections at the driving device should any waveforms be reflected back from the driven end of the line. Series termination preserves power since there is no current path to ground or Vcc as in the other meth- ods. However, this technique results in incident signals that transition slowly. It is also not appropriate for distributed loads due to the half-amplitude waveforms which exist at intermediate points along the line. RC termination represents a compromise between power con- sumption and effect on performance. Its principle of operation is similar to parallel termination, but the capacitor blocks the DC component of the signal, thus reducing power consumption. However, the effectiveness of this method depends on the fre- quency and duty cycle of the application. RC termination also can be an expensive technique if implemented using discrete components rather than a network. Typical Usage While not every address, data and control line may require pull-up/pull-down or termination as part of the system’s design, the table below shows common practice for some popular devices.

Typical Application A typical application using a Bourns 801 RC Network in con- junction with a 10K ECL design is shown below. Vee is typically volts. The 801 network shown below can terminate up to 6 transmission lines and provides a 0.01 mF capacitor to reduce cross talk and feedthrough effects. The actual, effective delay and impedance due to loading from stubs or additional devices off the line will be: Tpd’ = Tpd Ö1 + Cd/Co Zo Zo’ = Ö1 + (Cd/Co) Where Co = intrinsic capacitance of the line Cd = capacitance due to loading and stubs off the line Tpd = basic propagation delay of the line Zo ....= basic impedance of the line To formulate a guideline for when line termination is necessary, take the ratio of the rise time or fall time and the two- way delay along the line. The maximum length for unterminated lines will result as follows: Lmax = Tr 2Tpd’ Where Tr = rise or fall time Tpd = propagation delay per unit length The above equation implies that the faster the edge rate or the higher the loading on the line (i.e., higher fanout), the more likely that termination will be necessary for a given line length. Parallel Termination For maximum circuit performance or distributed loads, parallel termination is the most appropriate technique. A parallel termi- nated line uses a resistor connected to -2 volts (ECL application) at the receiving end. The resistor value matches the characteris- tic impedance of the line (Zo), thereby producing zero reflection at the receiver. In addition, the terminating resistor also provides output pull down, so a separate pull down resistor at the driving end is unnecessary. Transmission Line Considerations In high speed circuit applications, the signal propagation delay (Tpd) and characteristic impedance (zo), along a printed circuit board line must be taken into consideration. In general, if the two-way delay along the line is greater than the rise or fall time of the signal, then controlled impedance techniques (i.e., termi- nation) must be utilized to prevent undesirable ringing or over- and undershoots. The delay and impedance can be calculated by knowing the intrinsic inductance (Lo) and capacitance (Co) of the line: Tpd = ÖLoCo Zo = ÖLo/Co Vcc1 Aout A1in Vee Vcc2 Bout B1in A1in A1in A2in A2in B1in B1in B2in B2in B2inA2in, MC10H118 MECL 10KH Vee TRANSMISSION LINES Vtt BOURNS 801 10K ECL TERMINATOR Bourns Emitter Coupled Logic Terminator 800 Series

ECLinPS Data, Motorola, Inc., 1987. Bourns 801, 802, and 804 conformal coated SIP resistor capacitor networks are designed to terminate 6 transmission lines using the parallel termination technique. A 0.01 µF capaci- tor(s) is provided in each network to help maintain a solid Vtt level within the package, mitigating any potential cross talk or feedthrough effects. The 804 circuit also contains a 0.1 µF capacitor for bypassing the Vee supply. Parallel Termination Technique Thevenin Equivalent Parallel Termination Parallel termination in ECL applications uses -2.0 volts as the terminating voltage. This represents a disadvantage since a separate Vtt power supply must be available (Vee = -5.2 volts, Vtt = -2.0 volts). For systems in which a separate -2.0 volt sup- ply is not available, the use of a Thevenin equivalent arrange- ment, although resulting in higher power consumption, provides a convenient solution. Bourns 803 and 805 conformal coated SIP resistor capacitor networks are designed to terminate 8 transmission lines using the Thevenin equivalent parallel termination technique. Again, a 0.1 µF capacitor is provided to help maintain a solid Vee level within the package, mitigating any potential cross talk or feedthrough effects. The 803 is designed for use with 10K ECL whereas the 805 is designed for use with 100K ECL. Bourns Emitter Coupled Logic Terminator 800 Series

Specifications are subject to change without notice.326 The Dual Terminator (or Thevenin equiva- lent) Network is commonly used for TTL dual-line termination and pulse squaring or ECL line terminations. In ECL line termina- tor, R2 functions as an emitter pull-down resistor and is normally tied to the most negative supply voltage to provide proper line currents. R1 is normally tied to ground and functions as the termination resistor and in parallel with R2 provides the charac- teristic impedance of the transmission line. This results in a zero reflection coefficient of this line to eliminate reflections. The Dual Terminator circuit is available in both SIP and DIP configurations, as shown below. Example: Network 4608X-104-221/331 where R1 values are 220W and R2 values are 330W . Rp = Parallel Resistance of Remaining Circuit (See diagram below.)

Testing of Dual Terminators Since the Dual Terminator circuit has many resistors in parallel, a direct pin-to-pin measurement for the values of R1 and R2 can be made using an ohmmeter with guard capabilities. The function of the guard pin is to apply and equal voltage across the adjacent (parallel) resistance path. When applied, current flow is eliminated allowing an accu- rate measurement of the resistor under test. Using the 8-pin SIP network shown, the testing method would be as follows: Test R1 Values To test the first resistor, connect the ohm- meter measurement leads between pin 8 and 2. Connect the guard lead to pin 1. R1 is now guarded and an accurate measurement can be made. To test the second R1 resistor, connect the measurement leads between pin 8 and pin 3. Connect the guard to pin 1 and make the resistance measurement. Continue this testing scheme for the remainder of the R1 resistors, always guarding pin 1. Test R2 Values To test the first R2 resistor, connect the ohmmeter measurement leads between pin 1 and pin 2. Connect the guard lead to pin 8. The first R2 resistor is now guarded and an accurate measurement can be made. To test the second R2 resistor, connect the ohmmeter measurement leads between pin 1 and pin 3. Connect the guard lead to pin 8 and make the resistance measurement. Continue this testing scheme for the remainder of the R2 resistors, always guarding pin 8. An example of the type of ohmmeter to be utilized that incorporates a guarded mea- surement capability. It must be noted that guarded measurements using ohmmeters are satisfactory measurements up to a ratio of about 10:1 between R1 and R2. Above a 10:1 ratio, accuracy is degraded and measurements can be incorrect because of inadequate guarding capability of the equipment. Unguarded Resistance Measurements In the case where no guarded ohmmeter is available, the individual resistors can be evaluated by comparing the unguarded resistance measurement to the theoretical value of the equivalent series-parallel circuit and determining the percent of error of each resistor.

• Match impedance between memory driver and the DRAM array.
• Minimize reflections and ringing in DRAM inputs.
• Prevent undershoot of RAS, CAS, and WE signals which may result in latch-up of DRAM inputs
• Improve system performance by allowing faster setting times for DRAM inputs. Need For Damping The address lines (RAS, CAS) and control lines (WE) of dynamic RAM arrays are driven in parallel, causing significant loading on the driver of the DRAM arrays. Each DRAM control input (WE) has capacitive loading between 5pF to 7pF, while each address line input has about a 10pF load. Thus each DRAM input can be modeled as a transmission line with distributed inductance and capacitance. If not properly ter- minated, signal reflections and ringing on the line will result, adversely affecting the performance of the memory system. The effects on signal transitions will be: 1. Increased settling time delay on low-to-high transitions. 2. Voltage undershoot on high-to-low transitions. Increased settling time due to ringing reduces system perfor- mance because the design has to allow for the settling delay before sampling the signal. Undershoot, by bringing the input voltage below 0 volts, can damage the driver IC as well as alter the DRAM’s internal address register contents, causing potential loss of data.

Specifications are subject to change without notice.332 Application Guidelines Termination of address and control lines is typically accom- plished with low-valued resistors placed in series at the driver output. Selection of the proper resistance value is performed in two steps: approximation of the proper resistance using trans- mission line equations, and secondly, through trial and error, changing the resistance value to account for real world devia- tions such as PCB vias and bends. The appropriate transmission line equations are as follows: Zo = characteristic line impedance (microstrip) 87 5.98h= In ohms Td = propagation delay of the line = 1.017 Ö0.475er + 0.67 ns/in. Co = trace capacitance = 1000 (Td/Zo) pF/in. Cd = equivalent trace capacitance associated with each DRAM. It takes 0.5 inch to interconnect one DRAM. = 3.5pF/0.5 in. = 7 pF/in. Zo’ = effective characteristic impedance, accounting for capacitive loading of the DRAMs. Zo = Ö1 + Cd/Co Td’ = effective propagation delay, accounting for the capacitive loading of the DRAMs Td = Td Ö1 + Cd/Co where er = relative dielectric constant of the PCB’s glass epoxy layer h = distance from the trace to the ground plane w = width of trace t = thickness of trace (Ref. MMI Systems Design Handbook, pp. 10-5 and 10-6.) For example, for a trace with the following characteristics: er = 5 (for G10 glass epoxy) h = 30 mils w = 15 mils t = 3 mils then, Zo = 85 ohms Td = 0.15 ns/in. Co = 1.76 pF/in. Zo’ = 38 ohms Td’ = 0.35 ns/in. Thus on a theoretical basis, the design will require the resis- tance of 38 ohms to match the trace impedance of the PCB. However, the actual impedance will differ from this theoretical value due to the non-ideal characteristics of the PCB trace geometry (i.e., bends, curves and vias in the trace), as well as the manufacturing variations inherent in the components and materials. Therefore, a trial-and-error process must be employed in order to optimize the value of the damping resistor. The procedure involves selecting various values around the calculated value and observing the resulting waveforms on an oscilloscope. Choose the value that best balances the reduction in ringing/reflection and the reduction in speed: a large resis- tance value provides better damping, but will also add delay by slowing the edge rate. Typically, resistance values for memory damping will be in the range of 10 ohms to 50 ohms, with the most common values in the 20 ohm to 30 ohm range. Since memory damping is a type of series termination, distrib- uted loading along the line will not be possible. That is, the entire lumped load must be located at the end of the line, with no other loads along the signal path. This will guarantee that the waveform will remain undisturbed as it travels along the line. For related reasons, the placement of the series damping resistor should be as close to the driving device as possible. DRAM Applications

DRAM Applications

Specifications are subject to change without notice.334 Thin film is the preferred generic description for the field of micro-electronics in which conductive, resistive, and/or insulat- ing films are deposited or sputtered on a ceramic or other insu- lating substrate. The films can be deposited either in a required pattern or as a complete film layer and photoprocessed and etched to form the required pattern. The term “thin film” is derived from the fact that the deposited films are of the order of a few micrometers in thickness com- pared with the 10 to 50 micrometers for thick film. Often, thin film conductors are plated to improve conductivity. Thin Film Applications Thin film resistor networks typically find application in the ana- log world. The number one use of thin film is in controlling the gain on operational amplifiers. Some other applications are as a stable reference, stable voltage division, stable feedback loops and analog to digital or digital to analog conversion. These net- works may also be used for “wire-OR” pull-up, ECL output pull- down, TTL input pull-down, power down pull-up, open collector pull-up, digital pulse squaring, current summing amplifiers, TTL unused gate pull-up, TTL/MOS interfacing, coding and decod- ing, and telemetry. Thin film resistors in a network form offer additional benefits in performance. The resistors in a network are more closely matched in resistance and TCR and actually see reduced differ- entials of temperature in the end use application. These com- bine to provide improved tracking in networks. This improved tracking would be an advantage to the instrumentation and industrial control markets. Potential target markets for thin film include harsh environmen- tal conditions as well as the need for precision resistors. The improved ability to be stable at extended temperatures and the increased ability to handle moist environments are both benefits of the thin film offering. Target applications such as automotive and telecommunications will benefit from these capabilities. Thin Film Vs. Thick Film The basic distinction between thick film and thin film is the method of deposition of the metallization. In thick film, specially formulated pastes are applied and fired onto a substrate. The pastes are usually applied with a silk screen method and the substrate is of 96% alumina ceramic. In thin film, a layer of met- allization is sputtered onto a substrate and then a pattern is etched into the previously applied metal layer, the substrates are often 99.5% alumina ceramic,silicon, or glass. Thick film is an additive process where layers of termination and resistor materi- al are added to the substrate, while thin film is a subtractive process where the unwanted material is etched away in a suc- cession of selective photoetching processes. The use of photo- lithographic processes to form thin film patterns produce much finer lines and traces than thick film processes. Thin film is very appropriate for high density and high frequency applications. Thick and thin film technologies are well suited for low to medi- um volume custom circuits. Thick film has the advantages of lower cost (both of tooling up new designs and of production runs), of being able to handle more power, and of being able to service a higher range of ohmic values. Thin film has the advan- tages of tighter absolute and ratio tolerances and more environ- mentally stable components with lower noise and tighter TCR than thick film. Thin film technology is used wherever precision resistors are needed. Differential Op-amp Input Differential Op Amps are needed in electrically dirty environ- ments to reject noise transients that are picked up by wires. The differential Op Amps subtracts the noise out of the two signal wires. Thin film tracking capabilities are needed in these circuits to ensure that the input resistors do not affect the contents of the incoming signal.

It covers the popular soldering process currently in use and provides recommendations and cautions for each step. Since many variations of time, temperature, processes, cleaning agents and board types in use, you will want to verify your own system. Bourns does not recommend the backside mounting of passive components. The process steps, recommendations and cautions are based on Bourns surveys of users, equip- ment manufacturers and materials suppliers. No warranty expressed or implied is made in regards to the following recommendations. GENERAL Use the optimum solder paste for the pattern, printing process, and sol- der joint quality. RECOMMENDED Typical solder paste alloy is 63Sn/37Pb. RMA,No-Clean or Halide Free Water Soluble fluxes should be used. CAUTION Since solder paste usually contains a high percentage of activators, you must ensure adequate cleaning to remove all residues. Consult your solder paste supplier for cleaning meth- ods. When cleaning addi- tives are needed, only those that are Halide Free should be used. Adhesive Application GENERAL The adhesive must hold the unit in correct orientation upon placement and main- tain the correct position during any physical han- dling before the final sol- dering process. RECOMMENDED To assure positional stabili- ty, place a single dot of epoxy under the unit. CAUTION Use sufficient adhesive to assure stability through the cure process. Avoid overflow of epoxy onto solder pads and termi- nal areas. Excessive curing before placement may not allow full seating of the part causing incomplete solder connections. Network Placement GENERAL Use pick-and-place equip- ment with a vacuum nozzle ID that allows adequate suction to pick the unit out of the pocket cavity. RECOMMENDED Ensure nozzle inside diam- eter and vacuum levels are adequate to maintain suc- tion and part alignment. CAUTION Ensure parts are placed so that all leads are centered on the solder pads. Align the leads with the sol- der belt direction of travel to avoid the part body cre- ating a thermal shadowing effect. Excessive placement force to the part should be avoid- ed to minimize the risk of package damage. Flux Application Flow (Wave) GENERAL Use the correct flux to remove surface oxides, prevent re-oxidation and promote wetting. RECOMMENDED RMA (Rosin Mildly Activated) flux or Halide Free Water Soluble flux is recommended. CAUTION Avoid fluxes with Halide activators. Adhesive Cure GENERAL Heat/time cure should be accomplished using either an infrared radiation or a convection oven. RECOMMENDED Cure using the temperature profile specified by the adhe- sive manufacturer. CAUTION Use sufficient cure time to ensure complete adhesive transition from fluid to solid. Care should be taken to assure the placed units are not exposed to temperatures in excess of the manufactur- er's maximum. Do not exceed the maximum temperature rating of the component.

Solder Flow (Wave) GENERAL For maximum component reliability and performance, minimize the time of temp. exposure above 200° C. RECOMMENDED Typical alloy is Sn63/Pb37. A typical wave solder zone profile is 245˚C for 5 sec. CAUTION Always preheat before the soldier wave using the temperature for flux activation recommended by the man- ufacturer. Do not exceed 240˚C peak tempera- ture for dual wave solder process with a flow zone totaling 5 seconds. Minimize thermal shock by limiting temperature ramps to 3˚C/sec. and by stabilizing board and component temperature during preheating. Wash Solvent GENERAL Use solvent cleaning primarily for nonpolar contaminants such as rosin based flux residues. RECOMMENDED Use any suitable washing sol- vents that meet ODS require- ments. CAUTION Limit excessive direct spray pressure to 60 psi. Allow the assembly to suffi- ciently cool prior to the wash- ing operation for minimized thermal stress. Wash Aqueous GENERAL Use aqueous cleaning primarily for polar contaminants such as organic flux residues. RECOMMENDED Use De-ionized or Reverse Osmosis water with multistage rinsing. Post bake at 100˚C for 30 minutes to remove any resid- ual moisture. CAUTION Limit excessive direct spray pressure to 60 psi. Allow the assembly to sufficient- ly cool prior to the washing oper- ation for minimized thermal stress. Board Rework Technique GENERAL Excessive and/or repeated high temperature exposure may affect the component perfor- mance and reliability. RECOMMENDED Hot air reflow technique is pre- ferred. Use No Clean or Rosin based fluxes only, OA fluxes are recommended. CAUTION Avoid the use of wave soldering or soldering irons as a rework technique. Avoid repeated and excessive temperature exposure. PRE-HEATING (in air) SOLDERING GRADUAL COOLING (in air) 200°C 100°C 0°C ONE MINUTE MIN.
