[FAQ] DS80PCI102: PCIe RX Detect Pulse Timing

Part Number: DS80PCI102

Tool/software:

In PCIe applications, transmitter - while it is in high impedance - sends out pulses until it realizes a change in RC time constant of the response. For further details note  This FAQ. For further details, note scope shots of RX detect pulses below:
