Note*:
Trace lengths are suggested values based on TI lab measurements (taken with
output pre-emphasis enabled on both channels) to meet SATA loss and jitter spec.
Actual trace length supported by LVCP422 may be more or less than suggested
values and will depend on board layout, number of connectors used in the SATA
signal path, and SATA host and esata connector design.
