Hi,

Is it ok to connet HDP_SINK to 5V and HPD_SRC to 3.3V? Is it ok to connect SCL/SDA_SNK to 5V and SCL/SDA_SRC to 3.3V? Thanks!

Regards

David

    Hi David,

    HPD_Sink is expected to be a 5V input, the DP159 device will drive out a 3.3V HPD_SRC signal. Also, SCL_SNK/SDA_SNK are expected to be 5V signals where SCL_SRC/SDA_SRC signals are expected to be 3.3V.
