Comments
Defi ned by Gen2 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.
