TDP0604: TDP0604 TXFFE settings for D3 in DisplayPort Mode

Part Number: TDP0604

Tool/software:

We are operating the TDP0604 in DisplayPort mode.   There are TXFFE settings in the registers for D0, D1, and D2 at addresses 0x14, 0x16, and 0x18. Why is there no TXFFE settings for D3 (CLK) ??

    Hi,

    The TDP0604 must be configured as a linear redriver when enabled for DisplayPort mode. The linear range should be programmed to highest level (Dx_VOD = 0x3 and CLK_VOD = 0x3). The TDP0604 TX termination must be set to 100-ohms (TERM = 0x3) and TX bias must be set to ac-coupled (TX_AC_EN = 0x1). With TDP0604 being configured in linear mode, there is no TX FFE.

    Thanks
