Description

The IL3085 is a galvanically isolated, high-speed differential bus transceiver, designed for bidirectional data communication on balanced transmission lines. The device uses NVE’s patented* spintronic Giant Magnetoresistance (GMR) technology. A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. The wide-body version provides true 8 mm creepage. Narrow-body and QSOP packages offer unprecedented miniaturization. The IL3085 delivers at least 1.5 V into a 27 Ω load for excellent data integrity over long cable lengths. The device is compatible with

3.3 V input supplies, allowing interface to standard microcontrollers

without additional level shifting. Current limiting and thermal shutdown features protect against output short circuits and bus contention that may cause excessive power dissipation. Receiver inputs feature a “fail- safe if open” design, ensuring a logic high R-output if A/B are floating.

All voltages are with respect to network ground except differential I/O bus voltages. 2. Differential input/output voltage is measured at the noninverting terminal A with respect to the inverting terminal B. 3. Δ|V OD | and Δ|V OC | are the changes in magnitude of V OD and V OC , respectively, that occur when the input is changed from one logic state to the other. 4. Includes 10 ns read enable time. Maximum propagation delay is 25 ns after read assertion. 5. Pulse skew is defined as |t PLH – t PHL | of each channel. 6. Absolute Maximum specifications mean the device will not be damaged if operated under these conditions. It does not guarantee performance. 7. The relevant test and measurement methods are given in the Electromagnetic Compatibility section on p. 9. 8. External magnetic field immunity is improved by this factor if the field direction is “end-to-end” rather than to “pin-to-pin.”

However, NVE recommends that all integrated circuits be handled with appropriate care to avoid damage. Damage caused by inappropriate handling or storage could range from performance degradation to complete failure. Pinout Differences Between Packages QSOP and narrow-body version (IL3085-1E and IL3085-3E) are designed for application flexibility and minimum board area in dense PCAs. The wide-body version (IL3085E) has redundant ground pins for layout flexibility. QSOP and narrow-body versions provide separate isolated DE output (ISODE) and Transceiver Device Enable (XDE) input. ISODE follows the Device Enable input (DE). XDE can be used to enable and disable the transceiver from the bus side, or connected to ISODE to enable and disable the transceiver from the DE controller-side input. The QSOP and narrow-body versions also provide separate bus-side power supply pins— V DD2X for the transceiver module and V DD2I for the isolation module. These should be externally connected for normal operation, but can be used separately for testing or troubleshooting. The QSOP version also has an “ISOR” output that is isolated with respect to the controller-side “R.” This pin is used for testing and normally not connected, but could be used for a bus-side data output under special circumstances. The wide-body version has internal connections between the isolated DE output and the Transceiver Device Enable input, and well as between the two V DD2 bus-side power supply pins. The two internally-connected GND pins for each supply side provide layout flexibility. The ISODE output can be used in PROFIBUS applications where the state of the isolated drive enable node needs to be monitored, or for testing or troubleshooting. Power Supply Decoupling VDD1 and V DD2 should be bypassed with 0.1 µF typical (0.047 µF m inimum) capacitors as close as possible to the VDD pins. Maintaining Creepage Creepage distances are often critical in isolated circuits. In addition to meeting JEDEC standards, NVE isolator packages have unique creepage specifications. Standard pad libraries often extend under the package, compromising creepage and clearance. Similarly, ground planes, if used, should be spaced to avoid compromising clearance. Package drawings and recommended pad layouts are included in this datasheet. DC Correctness The IL3085 incorporates a patented refresh circuit to maintain the correct output state with respect to data input. At power up, the bus outputs will follow the Function Table shown on Page 1. The DE input should be held low during power-up to eliminate false drive data pulses from the bus. An external power supply monitor to minimize glitches caused by slow power-up and power-down transients is not required. Electromagnetic Compatibility The IL3085 is fully compliant with IEC 61000-6-1 and IEC 61000-6-2 standards for immunity, and IEC 61000-6-3, IEC 61000-6-4, CISPR, and FCC Class A standards for emissions. The IsoLoop Isolator’s Wheatstone bridge configurat ion and differential magnetic field signaling ensure excellent EM immunity. Immunity to external magnetic fields is even higher if the field direction is “end-to-end” (rather tha n to “pin-to-pin”) as shown at right.

NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 (952) 829-9217 www.nve.com Yo uTube.com/NveCorporation iso-apps@nve.com Receiver Features The receiver output “R” has tri-state capability vi a the active low RE input. Driver Features The RS-485 driver has a differential output and delivers at least 2.1 V across a 54 Ω load. Drivers feature low propagation delay skew to maximize bit width and minimize EMI. Drivers have tri-state capability via the active-high DE input. Receiver Data Rate, Cables and Terminations The IL3085 is intended for networks up to 4,000 feet (1,200 m), but the maximum data rate decreases as cable length increases. Twisted pair cable should be used in all networks since they tend to pick up noise and other electromagnetically induced voltages as common mode signals, which are effectively rejected by the differential receiver. Fail-Safe Operation “Fail-safe operation” is defined here as the forcin g of a logic high state on the “R” output in respon se to an open-circuit condition between the “A” and “B” lines of the bus, or when no drivers ar e active on the bus. Proper biasing can ensure fail-safe operation, that is a known state when there are no active drivers on the bus. IL3000-Series Isolated Transceivers include internal pull-up and pull-down resistors of approximately 30 kΩ in the receiver section (R FS-INT ; see figure below). These internal resistors are designed to ensure failsafe operation but only if there are no termination resistors. The entire V DD will appear between inputs “A” and “B” if there is no loading and no terminati on resistors, and there will be more than the required 200 mV with up to four RS-485 worst- case Unit Loads of 12 kΩ. Many designs operating below 1 Mbps or less than 1,000 feet are unterminated. Termination resistors may not be necessary for very low data rates and very short cable runs because reflections have time to settle before data sampling, which occurs at the middle of the bit interval. In busses with low-impedance termination resistors however, the differential voltage across the conductor pair will be close to zero with no active drivers. In this case the state of the bus is indeterminate, and the idle bus will be susceptible to noise. For example, with 120 Ω termination resistors (R T) on each end of the cable, and four Unit Loads (12 kΩ each), without external fail-safe biasing resistors the internal pull-up and pull- down resistors will produce a voltage between inputs “A” and “B” of only about 5 mV. This is not nearl y enough to ensure a known state. External fail-safe biasing resistors (R FS-EXT ) at one end of the bus can ensure fail-safe operation with a terminated bus. Resistors should be selected so that under worst-case power supply and resistor tolerances there is at least 200 mV across the conductor pair with no active drivers to meet the input sensitivity specification of the RS-485 standard. Using the same value for pull-up and pull-down biasing resistors maintains balance for positive- and negative going transitions. Lower-value resistors increase inactive noise immunity at the expense of quiescent power consumption. Note that each Unit Load on the bus adds a worst-case loading of 12 kΩ across the conductor pair, and 32 Unit Loads add 375 Ω worst-case loading. The more loads on the bus, the lower the required values of the biasing resistors. In the example with two 120 Ω termination resistors and four Unit Loads, 560 Ω external biasing resistors provide more than 200 mV between “A” and “B” with adequate margin for power supply v ariations and resistor tolerances. This ensures a known state when there are no active drivers. Other illustrative examples are shown in the following table:
