10 MOTOROLA ANALOG IC DEVICE DATA

The DC biasing scheme utilizes two VCC connections (Pins 3 and 6) and two VEE connections (Pins 14 and 11). VEE 1 (Pin 14) is connected internally to the IF and RSSI circuits’ negative supply bus while VEE 2 (Pin 11) is connected internally to the quadrature detector’s negative bus. Under positive ground operation, this unique configuration offers the ability to bias the RSSI and IF separately from the quadrature detector. When two ICs are cascaded as shown in the 70 MHz application circuit and provided by the PCB (see Figures 17 and 18), the first MC13155 is used without biasing its quadrature detector, thereby saving approximately 3.0 mA. A total current of 7.0 mA is used to fully bias each IC, thus the total current in the application circuit is approximately 11 mA. Both VCC pins are biased by the same supply. VCC 1 (Pin 3) is connected internally to the positive bus of the first half of the IF limiting amplifier, while VCC 2 is internally connected to the positive bus of the RSSI, the quadrature detector circuit, and the second half of the IF limiting amplifier (see Figure 15). This distribution of the VCC enhances the stability of the IC. RSSI Circuitry The RSSI circuitry provides typically 35 dB of linear dynamic range and its output voltage swing is adjusted by selection of the resistor from Pin 12 to VEE . The RSSI slope is typically 2.1 µA/dB ; thus, for a dynamic range of 35 dB, the current output is approximately 74 µA. A 47 k resistor will yield an RSSI output voltage swing of 3.5 Vdc. The RSSI buffer output at Pin 13 is an emitter–follower and needs an external emitter resistor of 10 k to VEE . In a cascaded configuration (see circuit application in Figure 16), only one of the RSSI Buffer outputs (Pin 13) is used; the RSSI outputs (Pin 12 of each IC) are tied together and the one closest to the VEE supply trace is decoupled to VCC ground. The two pins are connected to VEE through a 47 k resistor. This resistor sources a RSSI current which is proportional to the signal level at the IF input; typically, 1.0 mVrms (– 47 dBm) is required to place the MC13155 into limiting. The measured RSSI output voltage response of the application circuit is shown in Figure 12. Since the RSSI current output is dependent upon the input signal level at the IF input, a careful accounting of filter losses, matching and other losses and gains must be made in the entire receiver system. In the block diagram of the application circuit shown below, an accounting of the signal levels at points throughout the system shows how the RSSI response in Figure 12 is justified.

In the evaluation PCB, AC coupling is shown, however, interstage filtering may be desirable in some applications. In which case, the S–parameters provide a means to implement a low loss interstage match and better receiver sensitivity. Where a linear response of the RSSI output is desired when cascading the ICs, it is necessary to provide at least 10 dB of interstage loss. Figure 12 shows the RSSI response with and without interstage loss. A 15 dB resistive attenuator is an inexpensive way to linearize the RSSI response. This has its drawbacks since it is a wideband noise source that is dependent upon the source and load impedance and the amount of attenuation that it provides. A better, although more costly, solution would be a bandpass filter designed to the desired center frequency and bandpass response while carefully selecting the insertion loss. A network topology shown below may be used to provide a bandpass response with the desired insertion loss. 1.0n 0.22µ 1.0n Network Topology ARCHIVE INFORMATION ARCHIVE INFORMATION Freescale Sem iconductor, I Freescale Semiconductor, Inc.

11MOTOROLA ANALOG IC DEVICE DATA Quadrature Detector The quadrature detector is coupled to the IF with internal 2.0 pF capacitors between Pins 7 and 8 and Pins 9 and 10. For wideband data applications, such as FM video and satellite receivers, the drive to the detector can be increased with additional external capacitors between these pins, thus, the recovered video signal level output is increased for a given bandwidth (see Figure 11A and Figure 11B). The wideband performance of the detector is controlled by the loaded Q of the LC tank circuit. The following equation defines the components which set the detector circuit’s bandwidth: Q = RT/XL (1) where: RT is the equivalent shunt resistance across the LC Tank and XL is the reactance of the quadrature inductor at the IF frequency (XL = 2πfL). The inductor and capacitor are chosen to form a resonant LC Tank with the PCB and parasitic device capacitance at the desired IF center frequency as predicted by: (2)fc = (2π √(LCp)) –1 where: L is the parallel tank inductor and Cp is the equivalent parallel capacitance of the parallel resonant tank circuit. The following is a design example for a wideband detector at 70 MHz and a loaded Q of 5. The loaded Q of the quadrature detector is chosen somewhat less than the Q of the IF bandpass. For an IF frequency of 70 MHz and an IF bandpass of 10.9 MHz, the IF bandpass Q is approximately 6.4. Example: Let the external Cext = 20 pF. (The minimum value here should be greater than 15 pF making it greater than the internal device and PCB parasitic capacitance, Cint ≈ 3.0 pF). C p = Cint + Cext = 23 pF Rewrite Equation 2 and solve for L: L = 198 nH, thus, a standard value is chosen. L = 0.22 µH (tunable shielded inductor). The value of the total damping resistor to obtain the required loaded Q of 5 can be calculated by rearranging Equation 1: R T = Q(2πfL) The internal resistance, Rint between the quadrature tank Pins 8 and 9 is approximately 3200 Ω and is considered in determining the external resistance, Rext which is calculated from: Rext = ((RT)(Rint))/ (Rint – RT) Rext = 570, thus, choose the standard value. Rext = 560 Ω . SAW Filter In wideband video data applications, the IF occupied bandwidth may be several MHz wide. A good rule of thumb is to choose the IF frequency about 10 or more times greater than the IF occupied bandwidth. The IF bandpass filter is a SAW filter in video data applications where a very selective response is needed (i.e., very sharp bandpass response). The evaluation PCB is laid out to accommodate two SAW filter package types: 1) A five–leaded plastic SIP package. Recommended part numbers are Siemens X6950M which operates at 70 MHz; 10.4 MHz 3 dB passband, X6951M (X252.8) which operates at 70 MHz; 9.2 MHz 3 dB passband; and X6958M which operates at 70 MHz, 6.3 MHz 3 dB passband, and 2) A four–leaded TO–39 metal can package. Typical insertion loss in a wide bandpass SAW filter is 25 dB. The above SAW filters require source and load impedances of 50 Ω to assure stable operation. On the PC board layout, space is provided to add a matching network, such as a 1:4 surface mount transformer between the SAW filter output and the input to the MC13155. A 1:4 transformer, made by Coilcraft and Mini Circuits, provides a suitable interface (see Figures 16, 17 and 18). In the circuit and layout, the SAW filter and the MC13155 are differentially configured with interconnect traces which are equal in length and symmetrical. This balanced feed enhances RF stability, phase linearity, and noise performance. ARCHIVE INFORMATION ARCHIVE INFORMATION Freescale Sem iconductor, I Freescale Semiconductor, Inc.
