Working with the SN65DP149RSBT HDMI Re-Driver/Re-Timer which is connected to a FPGA.
We currently have the DDC connections directly through to the FPGA rather than passing through the chip. Is there is any consequence of leaving the SDA, SCL and HPD SRC/SNK pins floating?
From the datasheet, the HPD controls the power down command, but this can be disabled via register 0x09 bit 2 (pg. 33). Does the chip require the DDC/HPD to run through it in order for it operate properly or are you able to pass through video without any I2C running through the device.
