loop-back testing

The transceiver can provide a self-test function by enabling (LOOPEN to high level) the internal loop-back path.

Enabling LOOPEN causes serially transmitted data to be routed internally to the receiver. The parallel data

output can be compared to the parallel input data for functional verification. The external differential output is

held in a static state during loop-back testing.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. All voltage values, except differential I/O bus voltages, are with respect to network ground.

2. This parameter is tested in accordance with MIL-PRF-38535.
