help for TFP410-EP internal DE generator

Other Parts Discussed in Thread: TFP410-EP, TFP410

Dear,
we plan to use TFP410-EP in out project, and we kown that the internal DE generator of TFP410-EP has the limitation for H_RES <= 2047 & V_RES <= 2047.
as per SMPTE-274M & SMPTE-296M, the internal DE generator can't support 1080p60/50/30/25/24, neither 720p30/25/24.

so anyone can help us to confirm the below:
1) TFP410-EP can support 1080p60/50/30/25/24 and 720p30/25/24 and works if we disable internal DE generator and use external DE pin input ?
2) TFP410-EP can NOT support 1080p60/50/30/25/24 or 720p30/25/24 even if we disable internal DE generator and use external DE pin input ?
3) If it works when disable internal DE generator and use external DE pin input, make sure the TFP410-EP output completed, non-cropped video frame (incompleted or cropped video frame not accepted)?

Thank you!

Hello,
The TFP410 does not crop video.
It does not care about resolution, it is just a serializer, it will take the parallel inputs an converts them into a TMDS stream with pixel frequencies from 25MHz to 165MHz.

So, as long as the signals are within the frequency of operation range it will support any resolution. For example a standard resolution of 1920x1080@50 fps will require a pixel clock frequency of 141.5MHz which is supported by the TFP410 as it is within the 25-165 MHz range.
