SATA signal conditioning in a 20-QFN
The Texas Instruments SN75LVCP601RTJT is a two-channel SATA buffer and re-driver that takes a CML input and delivers a VML output, rated for 6 Gbps per lane. It integrates input equalization and output de-emphasis to compensate for PCB trace and cable losses on SATA Gen3 links. The 323 ps typical propagation delay is low enough to stay within the bit-time budget for backplane routing.
Signal conditioning: equalisation and de-emphasis
Input equalisation boosts high-frequency content attenuated by the channel; output de-emphasis reduces the amplitude of the first few bits after a transition to pre-compensate for cable losses. Together they extend the reachable trace length or cable distance beyond what a plain buffer can manage. The part has no programmable settings listed — conditioning is fixed, so verify it matches your channel loss profile.
