From my understanding there is 5V that is sent from the HDMI source and then the HDMI sink sends that 5V back to the HDMI source on the HPD pin. The device pin mapping can be routed to either HDMI Type D or Type C connector. (Refer to the carrier I/O board schematics for how to do that. The MAX9406 operates from a 3V to 3. Design Guidelines for HDMI Intel® FPGA IP x. So HPD voltage division circuit is suggested as shown in Figure 3, serial resistor is 10K while shunt-down resistor is 18K.

We are using the ADV software driver to configure the ADV7623-P as a HDMI switch with automatic sensing if there is signal on an input or not. Normally the Tx will not transmit until it sees a valid HPD signal (high) and detects the proper termination on the TMDS clock line. 8V) We measured HDMI_HDP voltage is 4. A first pin on a HDMI connector provides a pulsed hot pin detect (HPD) signal to the device when connected to an appliance, and a second pin receives the signal back from the device when connected and causes the intermittent HPD signal to be replaced by a DC supply when connected. You can override these checks via software. In this case a flexible power saving mode can be implemented. We found a similar topic on JP6. Driving ENABLE low breaks the connection between the input and output busses. 3V tolerance, but HPD at HDMI interface is +5V.
