LMH0397: How to enable Cable EQ Bypass Override

Part Number: LMH0397
Other Parts Discussed in Thread: LMH1297,

Dear Support,

Could you help to clarify how to program the bit3 of the 0x27 register?

Page 9 of our programming guide, it's said that the override feature is enabled with the value 08(dec), so setting a '1' in bit3, is that correct?

While page 38 it's written:

Override eq_bypass value to analog core
0 = Enable EQ Bypass override. Value of EQ Bypass Control determined by Reg 0x27[2].
1 = Disable EQ Bypass override

Regards,

    Hi TISL,

    Thanks for pointing this out. Page 38 is not correct and it is the other way around:

    1 = Enable EQ Bypass override. Value of EQ Bypass Control determined by Reg 0x27[2].
    0 = Disable EQ Bypass overrid

    Please follow page 9 of the programming guide. We will make this change on the next release of the LMH0397 programming guide. Please note LMH1297 programming guide is correct(these are the same devices but running at different data rates).

    Regards,, Nasser
