Comments
Defi ned by PCIe 2.0 spec.
VRX-DIFFp-p = 2*|VRX-D+
- VRX-D-|. Applies to IN_S
and RX_IN signals.
VCM-AC-pp = |VRX-D+ +
VRX-D-|/2 - VRX-CM-DC.
VRX-CM-DC = DC(avg) of
|VRX-D++VRX-D-|/2
VCM-AC-pp includes all
frequencies above 30kHz.
Rx DC Differential Mode
impedance
Required IN_D+ as well as
IN_D- DC impedance (50 
± 20% tolerance). Includes
mux resistance.
Intended to limit power-up
stress on PCIE output buffers.
