Evaluation of Receiver Operation During Ground Shifts
This chapter explains how to introduce ground shifts between the driver and the receiver to test the
receiver operation over its full common-mode voltage input range.
LVDS driver outputs have an offset voltage of approximately 1.2 V. The SN65LVDS32 receiver complies
with the TIA/EIA–644 standard. It correctly detects the logic level of the input signal when 100 mV of
differential signal is present at its input, and the input common-mode voltage is between 0 V and 2.4 V.
(The actual input common-mode range is also dependent upon the differential input voltage; see
recommended operating condition in the data sheet for dependency.) The SN65LVDS32B provides
operation over an input common-mode voltage range of –2 V to 4.4 V, whereas the SN65LVDS33 extends
the operation to an input common-mode voltage range of –4 V to 5 V. Both the above mentioned receivers
are equipped to correctly detect the input state with a 50-mV differential signal at its input.
input state with a 50-mV differential signal at its input. All EVMs can be used to evaluate the receiver
operation in the presence of ground shifts between the driver and receiver. Testing of EVMs that host a
SN65LVDS32B or a SN65LVDS33 will demonstrate the extended range operation of these devices.
Perform the following steps to demonstrate operation during ground shifts.
1. Remove the jumper shorts on jumpers J5 and J6.
Three dc power supplies will be used for this test.
2. Using the first power supply (PS1), apply 3.3-V power to the driver section of the EVM (via connectors
P17 and P18).
3. Using the second power supply (PS2), apply 3.3-V power to the receiver section of the EVM (via
connectors P19 and P20).
4. Tie the third power supply (PS3) between the grounds of PS1 and PS2.
5. Initially set PS3 to 0 V.
6. Input a test signal to the driver while monitoring the output of a receiver (refer to Chapter 3 ,
Point-to-Point Transmission).
7. Vary the ground shift between the driver and the receiver via adjustments to PS3.
