Hello

I am using my design SN75DP159(X2) as retimer to HDMI and DVI .

1. What is the I2C address of the SCL/SDA_SRC?

2. What is the voltage level of the SCL/SDA_SRC?

3. What is the voltage level of the SCL/SDA_CTL?

1. SCL/SDA_SOURCE is source side DDC, it passes DDC traffic from SCL/SDA_SINK, there is no I2C address
2. Please refer to section 6.3, AUX and I2C pins voltage, max voltage is 3.6V for SCL/SDA_SOURCE.
3. Please refer to section 7.5.3

Thanks
David

Just to be sure, SCL/SDA Sink connect between the DVI/HDMI connector to SN75DP159 and SCL_SRC should be connect betweenthe SN75DP159 toMCU/FPGA (with pull up resistor to 3.3V), right?

Please see Figure 31 and Note 1 in the SN75DP159 datasheet on the SCL/SDA_SNK and SCL/SDA_SRC connection.

Thanks
