SN75DP130: SN75DP130 VOD/ Pre-emphasis setting

Part Number: SN75DP130

Hi team,

SN75dp130 can bypass input by default? (00 – Voltage swing level 0 (default), 00 – Pre-emphasis level 0 (default))

Or it should be set VDO: level1, Pre-emphasis level 0?

    DP130 will not bypass input. Voltage swing level 0 and pre-emphasis level 0 means DP130 applies nominal 340mVpp and 0dB pre-emphasis to the signal. You can start with voltage swing level 1 which is 510mVpp.

    Since DP130 is a limited redriver with its own SWING and Pre-emphasis level, the actual value of DP130 SWING and Pre-emphasis level may not be the same as the actual value of source SWING and Pre-emphasis level.

    Thanks
