6.14.2 SATA Interface
This section provides the timing specification for the SATA interface as a PCB design and manufacturing
specification. The design rules constrain PCB trace length, PCB trace skew, signal integrity, cross-talk,
and signal timing. TI has performed the simulation and system design work to ensure the SATA interface
requirements are met.
