Decoding AHD with ADV7280(A)

Thread Summary

The user inquires about the ADV7280A's capability to support higher resolution AHD video at 50Hz. The final answer indicates that while several Analog Devices decoders support AHD 1.0 and 2.0, none support AHD 3.0. The ADV7181D and ADV7844 are not recommended for new designs. The accompanying answer clarifies that AHD video requires higher bandwidth processing, which is not feasible with single-ended configurations.

Hello,

Question about AHD and 7280A, Can it successfully support higher resolution @50Hz even if not 'standard' (lower frame rate). I ask before going into some changes for WxH setting in the lower driver configuration. Just reading Status register 1,2 and 3 looks not obvious if internal circuitry adjusted to H/V Sync, INST_HLOCK(1), SD_OP_50Hz(1)
