Part Number: DS90UB925Q-Q1

Hi everyone

We need to convert data from FPDLink III ( the serializer DS90UB925) to CSI 8-bit Parallel Camera , We prepare to use seserializer DS90UB914 to achieve ;

The DS90UR925 can compatible with DS90UB914 ?

If not - can we propose a cheap (small…) solution converting FPDLink III to CSI 8-bit Parallel Camera ?

Hi,

914 can't be used here: 1. 914 output is NOT CSI I/f; 2. 914 can't be linked with 925 (pls check any data sheet from either 914 or 925).

you can use DS90UR910 in this case which has CSI2 output port and can work with 925.

Regards,

Steven

Hi ,

The Processor No CSI- 2 interface, DS90UR910 cannot meet the requirements,

the Processor only BT656 parallel interface, as the chart, could you recommend a corresponding solution series DeSerializer ?

hello,

in your first description, CSI is mentioned but you also select 914, so this made us confuse.

now you can use 925/926 or 913a/914a to transmit the BT656 signals.

regards,

Steven

5772050,

For SerDes solution, pls just describe the issue based on I/f type, it would be clear.

regarding your issue, if the de-ser's parallel I/f is LVCMOS, and the ser. is 925, you only have one option UB926. so pls use 926 in your case.

regards,

Steven
