Part Number: DS90UB928Q-Q1

Dear Team,

May I know the Horizontal Sync and Vertical Sync pins of DS90UB928Q-Q1.

I need to connect it to my LVDS.

The LCD has dedicated Horizontal Sync and Vertical Sync pins.

Can I use any GPIO for HS and VS signals

Regards

Hello Hari,

the 928 is an oLDI DES, hence does not have dedicated pins for VS and HS. If you want dedicated pins, then you should use a parallel interface DES such as the 926.

Hello Hari,

I believe either the UB928 or the UB948 are the right parts for you (Based on your PCLK).

Normally HS and VS come integrated in the LVDS signal Data-Lane 2, as you can see below (from UB928 d/s). You shall be using the 24-bits MAPSEL = H mode.
