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.
