Hi team,

My customer is seeking the HDMI to LVDS solution.

Could you help check if the TFP401AMPZPEP can support 64RGB*60，120Hz application?

Please help show how to calculate the required pixel rate for this application, thanks.

I would forward this forum to customer so that they could add follow up questions if they have.

Best regards

Hello,

There is an FAQ that can help explain the potential solutions for HDMI to LVDS conversions.

Please see the following solutions here:

https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1320286/faq-potential-ti-solutions-for-video-protocol-conversion?tisearch=e2e-sitesearch&keymatch=faq%3Atrue

The DVI RX output is configurable with pin “PIXS”. When PIXS is Low, RGB data is output on 24 bits (QE[23:0]). When PIXS is High, RGB data is split odd/even on 48-bits (QO[23:0] & QE[23:0]). The 4 additional bits are VSYNC, HSYNC, DE, and ODCK. If you are wanting to pass 64 RGB bits, as I understand above, the TFP401A won't be able to support.

Thanks,

Zach
