TMDS181: Four design queries from customer

Part Number:TMDS181

Hi,

My customer have been looking at the TMDS181 redriver/timer IC  but have some questions in that regard. Could you please look into this?

1. When running device in I2C mode the TX_TERM_CTL setting is fully defined by software. Is there a way to automatically switch termination in this case? Setting “01” is listed as reserved. I2C gives highest flexibility w.r.t. setup however HW mode has automatic termination when TX_TERM_CTL = NC.
2. Register 0x0A has bit 7 defining “Application mode selector” between 0: Source and 1: Sink (default). What does this change in the device configuration?
3. The “EyeScan” Tool has options to set DDC slew rate – however the registers are not specified in the datasheet?
4. We might be going for DDC snooping. However this puts extra capacitive load on the lines. How much is the capacitive load on the SDA_SRC/SCL_SRC and SDA_SNK/SCL_SNK pins?

Thanks. B.r /M.A.M
