Proposed OCP NIC 1.7 Inputs for PCIe Budgets

PCIe CEM 7.0 Draft 0.5

Page 17 of the

Draft 0.5 Spec

Now Rev 1.0

Also refer to PCIe Base Spec 7.0 section: 8.3.5

The following informative limits for PCIe Gen 7 at 128 GT/s are to be specified. Current investigative efforts are ongoing by the OCP NIC sub-group to determine a specified set of values to cover Insertion Loss, Return Loss, PSNEXT and PSFEXT.

New Section 6.1.3.4 PCIe Gen 7 Informative Limits

Proposed OCP NIC 1.7 Inputs for Informative Limits

SNIA re-open SFF-TA-1002 to include Gen7
