Other Parts Discussed in Thread: DS90UB934-Q1

We use DS90UB933-Q1 IC, and the input signal is BT656.(another box,receive IC is DS90UB934-Q1)

BT656 has 8 bit input, but 933 has 10 or 12 bit input, how can I connect 8 bit to 10 bit? Other bit pull down?

Unused signal HSYNC and VSYNC pull up or pull down?

Hello Mick,

You can connect 8-bits and leave the rest.

Please do not pull-low or high, any unused inputs should be left as No Connect.

Thanks for your reply!

Connect BT656 bit 0-7 to 933 bit 0-7 or bit 1-8 or bit 2-9 ......, or other?

If I should refer to 934 connection mode？

IF you connect 0-7 to 933, then also 0-7 on the 934 side
