Notes:

1. A modified PI2PCIE2422 application board with 16-inch differential trace is used for Eye management.

2. Agilent N4902B BERT is used to generate a K28.5 pattern at 5 Gbps with 500mV single-end swing.

3. To create the P12PCIE2422-free test condition, the PI2PCIE2422 chip is removed and a wire is connected between the trace

and output

probe.
