DP or HDMI to 2560x1XXX

Hi,

I've been hunting around for a DP or HDMI to LVDS bridge that supports 2560x1XXX resolution to hook up to an AUO panel.

Does TI have such an offering?

The next best thing I can find so far is the STDP4020 but information on that is quite scarce.

Regards,
David.

    Hi David, which AUO panel model# do you have in mind?  And how many LVDS channels (or differential pairs for data) does it use?

    Thanks,

    Hi, Thanks for the reply. The panel is a 2560x1080 quad lvds so it looks like TI can't help (model no T5706DC01) ParadeTech have the DP628 that looks good too. Shame none of them are as accessible as TI!

    Another option would be to adopt a 2 chip approach, using a TI based product and perhaps a PixelWorks PA136PD.  Again, we are a smaller company that these larger companies tend to not work or price of entry is massive.

    Unfortunately, TI doesn't have any quad-channel LVDS serializers.  I think you'd run into issues trying to use two dual-channels in parallel, due to propagation delay differences and the receiver's skew tolerance.  I've seen skew tolerance spec'd in some dual-channel LVDS panels from LG to be up to 1/7th the clock (1 LVDS bit), which is hard to achieve using two separate transmitter devices.

    Best regards,
