TMDS181: Strap pin selection for Max

Part Number: TMDS181

Hi,

We are using the TMDS181RGZT in our board, and we are using it in the Pin strap mode.

What would be the best combination of the EQ_SEL & PRE_SEL.

Am looking to pass the video data for 4k60fps resolution.

Can anyone please help?

Thanks & Regards,

Nanjunda M

    You can use these as your starting values:

    - SIG_EN = Low (the signal detect circuit disabled)
    - EQ_SEL = NC (adaptive EQ)
    - PRE_SEL = NC (0dB)
    - VSadj = 7.06kΩ
    - TX_TERM_CTL = NC (automatically selects the termination impedance)

    But these values are application dependent, you will have to tweak them depending on your testing result.

    Thanks

    Hi David, 

    Could you also please help me with settings for SN75DP159RSBT & SN65DP141RLJR (the equalization and pre-emph settings).

    Thanks & Regards,
