Hi AE,

The current Pre-Channel total and Post-Channel total are as follows.
Could you help recommend the appropriate settings for CEQ1, CEQ0 and SSEQ1, SSEQ0?

TUSB1142	F	F	1	F	2678 mils	1387 mils

Hi,

If you are using the TUSB1142, its best to keep the post-channel loss compensated by AEQ.

The pre-channel trace length of 2678 mils should be compensated by SSEQ of 1.9dB to 5dB depending on the loss of the board.
