Pin planner or Assignment Editor Name
Transmitter High-Speed Compensation
Description
Specifies if the power distribution network (PDN) induced inter-symbol interference (ISI) compensation
is enabled or disabled in the TX driver. When enabled, it reduces the PDN induced ISI jitter, but increases
the power consumption. Use this feature for high speed applications. It defaults to ENABLE for non-PCIe
modes.
