Description

The IL3185 and IL3122 are galvanically isolated, di fferential bus transceivers designed for bidirectional data communication over balanced transmission lines. The devices use NVE’s patented* IsoLoop spintronic Gian t Magnetoresistance (GMR) technology. The IL3185 deli vers at least 1.5 V into a 54 Ω load, and the IL3122 at least 2 V into a 100 Ω load for excellent data integrity over long cables. These devices are also compatible with 3 V input supplies, allowing interface to standard microcontrollers without additional level shifting. Both the IL3185 and IL3122 have current limiting an d thermal shutdown features to protect against output short circuits and bus contentions that may cause excessive power dissipation. The receivers also incorporate a “fail -safe if open” design, ensuring a logic high on R if the bus lines are disconnected or “floating.” Selection Table Model Full/Half Duplex No. of Devices Allowed on Bus Data Rate Mbps Fail-Safe IL3185 half 32 5 yes IL3122 full 32 5 yes R RE A B Z R RE Y IL3122 IL3185 A B VCOIL2 VCOIL1 VCOIL1 VCOIL2 DE D DE D

Proper biasing can ensure fail-safe operation, that is a known state when there are no active drivers on the bus. IL3185 and IL3122 Isolated Transceivers include internal pull-up and pull-down resistors of approximately 30 kΩ in the receiver section (R FS-INT ; see figure on following page). 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 termination resistors, and there will be more than the required 200 mV with up to four RS -485/RS-422 worst-case Unit Loads of 12 k Ω. Many designs operating below 1 Mbps or less than 1,000 feet are unterminated. Te rmination resistors may not be necessary for very l ow 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 pul l-down resistors will produce a voltage between inputs “A” and “B” of only about 5 mV. This is not nearly enough to ensure a known s tate. 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 cond uctor pair with no active drivers to meet the input sensitivity specification of the RS-422 and RS-485 standards. 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 immun ity 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 value s 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 variations and resistor tolerances. This ensures a known state when there are no active drivers.
