I'm working with a hardware team on a new design using the ADV7619. We seem to have discovered an anomaly in the documentation regarding HPA_A and HPA_B.
In the ADV7619 Reference Manual UG-237 Rev C. it is stated (pages 13 & 31) that HPA_A and HPA_B are open drain and need pull-up resistors.
However in the ADV7619 Datasheet Revision C these pins are shown as ordinary digital outputs (page 4) and as 5 V tolerant (page 12).
Please can you clarify if they are open drain or ordinary outputs.
