Part Number: DS90UB948-Q1

Dear Team,

As shown in the red part of the figure below
1. What do REPEATER=0 and=1 mean respectively;
2. If RIN1 single ended input is used as the input, Coax is used as the input, and the speed is 20Mbps, is the voltage of MODE_SELL1 configured as 0.974V or 2.642V;
Could you please help confirm? Thank you.

    Hi Allen,

    The primary purpose of repeater mode is to extend transmission across multiple links to support multiple display devices. If repeater mode is used with a coax configuration, MODE_SEL1 must be strapped to 2.642 V.

    Hope this helps. Let me know if you have further questions.
