TFP401A: From TMDS to parallel 16bit

Part Number: TFP401A
Other Parts Discussed in Thread: TFP401, THS8200

Dear, Support Team.

We would like to use TFP401A to convert from input 1080p/60fps TMDS/YPbPr(4:2:2) format to output 16bit parallel/YPbPr(4:2:2) format.

Could you tell me the mapping of the output pins of the TFP401A?

Best Regards,

The TFP401 is a DVI (Digital Visual Interface) compliant digital receiver that is used in digital flat panel display systems to receive and decode TMDS encoded RGB pixel data streams. It will not support YPbPr(4:2:2) format.

Thanks

Hi David-san

Thank you for your reply.
I understand the functionality of the TFP401's DVI receiver.
If you have a device that supports TMDS to YPbPr(4:2:2) please let me know.

You can use TFP401A with THS8200, https://www.ti.com/lit/ds/symlink/ths8200.pdf, to achieve TMDS to YPbPr conversion.

Thanks

Hi, David-san

Thank you for your advice.
We use TFP401A and THS8200 together.
Also refer to Figure 6-2. 20-/16-Bit YCbCr 4:2:2 Data Format (16-Bit Operation Shown) in the attached datasheet.
