PCIe Preferred PCIe_PHY_RX SCP Register Settings Updated

CRITICALITY

Low

DESCRIPTION

The “Preferred PCIe_PHY_RX SCP Register Settings” table in the Technical Reference Manual (TRM) has been updated with values to select fully adaptive equalization and a second-order clock recovery algorithm. These changes have been shown to enhance PCIe receiver (RX) jitter tolerance for 5GT/s operation.

GUIDELINES

Software can be updated to the new preferred settings, especially for 5GT/s operation, if enhanced RX jitter tolerance is desired.
