Comments
Defi ned by Gen2 spec.
VRX-DIFFp-p = 2*|VRX-
D+ - VRX-D-|. Applies to
IN_D 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 Ω +/- 20% tolerance).
Includes mux resistance.
Intended to limit power-
up stress on PCIE output
buffers.
