SN75DP130: Support HBR2

Part Number: SN75DP130

Hi Sirs,

Sorry to bother you.

Two question on DP130

1. Do we need to extra programming EQ for HBR2 Data rate?
Because we saw default is on HBR

2. We use pin4.5 to configuration EQ.
After power off, the setting will save on register on next turn on or we need configure again?

Thanks!!

    Hi Shu-Cheng,

    In default mode. DP130 monitors AUX channel to configure itself, here you don't need extra programming.
    If you disable DP130's link training, you will have to write DP130's DPCD registers by I2C

    DP130 has a volatile memory, everything you write on the registers will be erased at power off.

    Regards
