Part Number: DS90UB953-Q1

Regarding to snla270a, the maximum RX PCLK of RAW10 mode for 914A/934 is 133MHz in the table 15.

I thought maximum PCLK for 914A/934 is up to 100MHz.

Does 914A/934 actually accept PCLK up to 133MHz?

Hello Takuma,

you are right, the 934 can support PCLK up to 133MHz but only if paired with the 953 in Backward (DVP) mode.
I do not believe this is also valid for the 914A but I can double check.

hello Hamzeh,

Thank you for reply. could you double check about 914A limitation?

Also i want to confirm if 934 can support 133MHz. I dont see the description in the 934 datasheet.

Hello Takuma,

as I said, the 934 can support up to 133MHz PCLK only if paired with the 953. It is not mentioned in the 934 d/s because it is a special application with the 953 in DVP mode. So it is just mentioned in the 953 DVP mode App note.

The 914A can't support this. Anyway, we do not recommend using the 914A in any new design. please use the 934 instead.
