For the Card Electromechanical Specification, this ECR increases Cin, the maximum input pin capacitance on 3.3 V logic signals (applies to PERST# and PWRBRK#) from 7 pF to 20 pF (see CEM Table 3).
For the M.2 specification, this ECR increases M.2 CIN, the maximum input pin capacitance for both 3.3 V logic signal (applies to PERST#, see M.2 Table 4-1) and 1.8 V logic signals (applies to PERST# and PEWAKE# (when used for OBFF signaling), see M.2 Table 4-2) from 10 pF to 20 pF. This capacitance increase is large enough for known upcoming lithographies.
It had not been clear what the measurement point was for CIN in CEM or M.2 specifications. This 18 ECN extends the COUT measurement point specified in M.2 to apply to CIN and COUT for both 19 CEM and M.2 specifications.

The PCI Express OCuLink Specification allowed the cable assembly to consume the entire budget. The Transmitter and traces routing to the OCuLink connector need some of this budget. The PCI Express Card Electromechanical Specification Revision 3.0 assigns 1.6 ns to the total interconnect lane to lane skew budget.

2. The PCI Express Base Specification is updated to define an optional mechanism to indicate support for Emergency Power Reduction and to provide visibility as to the power reduction status of a Device.
