Hi TI team,

I like to get some info how I can tune RX EQ & TX amplitude/emphasis with this EVM. Pls advise.



  • Jun

    The VSADJ, PRE, EQ, and ERC are controlled by external 10k pulled up to 1.8V or 10k pulldown. 

    VIH -> 10k pullup to 1.8V

    VIL -> 10k pull down to ground

    VIM -> floating

    Please refer to Table 1 in the datasheet for the EQ selection. 

    Please refer to Table 2 for the ERC selection

    Please refer to Table 3 for the VSADJ and Pre selection

    You can use the example in section 8.2 as your tuning guide.
