Clock Request: Serial Reference Clock request signals for PCIe* 100 MHz differential clocks

The SRCCLKREQ*# signals can be configured to map to any of the PCD PCI Express* Root Ports while using any of the PCD CLKOUT differential pairs.

XTAL_​IN

I

Crystal Input: Input connection for 38.4 MHz crystal to Processor.

XTAL_​OUT

O

Crystal Output: Output connection for 38.4 MHz crystal to Processor.

CLK_​S_​RCOMP

Analog

Differential Clock Bias Reference: Used to set BIAS reference for differential clocks

Notes:
  1. SSC = Spread Spectrum Clocking
  2. The SRCCLKREQ# signals can be configured to map to any of the PCI Express Root Ports while using any of the clock output differential pairs.
  3. Above consideration is not applicable when designing platform that does not use common motherboard concept.
