DisplayPort multiplexer for bidirectional video
7.4 HPD signal path
The HPD signal path, unlike the Main Link and AUX/DDC paths, uses active LVTTL logic
rather than passive switching. As shown in Figure 7, the topology follows that of the
Main Link and AUX channels but with the signal direction in reverse direction (since the
HPD signal direction is always from sink to source). When PATH_SEL is LOW, output
HPD_C follows and re-drives input HPD_D and similarly HPD_A follows the logic state of
input HPD_B. An integrated 200 k
Ω resistor (RPD_HPD) between HPD_B and GND
ensures a logic LOW when no device is connected to Port B. When PATH_SEL is HIGH,
HPD_B becomes an output and follows the logic state of HPD_D. Please also refer to
Section 7.6 for specific details on the HPD filtering function.
