Description
Pericom semiconductor's PI2PCIE2422 is an 8 to 4 channel differential multiplexer/demultiplexer featuring 8-channel passthrough. It supports two full PCI Express lanes at 5.0Gbps Gen II performance. With the select control input low Port A connects to Port B, and Port C connects to port D for an 8-channel differential pass-though. When the select control input is high Port A connects to Port D, and Port B and Port C are in a high-impedance state. The mux/demux function is between Port A and Ports B or D as determined by the select input control.

Notes: 1. CL = Load capacitance: includes jig and probe capacitance. 2. RT = Termination resistance: should be equal to ZOUT of the Pulse Generator 3. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control. Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control. 4. All input impulses are supplied by generators having the following characteristics: PRR MHz, ZO = 50, tR 2.5ns, tF 2.5ns. 5. The outputs are measured one at a time with one transition per measurement.

PCI Express Application Specific Measurements and Test Set-up
Figure 6: the test set-up for the PI2PCIE2422 eye test
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. 4. An Agilent Infinuum 54855A is used and Serial Data Analysis software is ran to capture the Eye.
