hello，team

I will use DS90UB914A as a deserializer

I have a question about the PCB layout

I want to match the length of 10bit data +hs+vs+clk(96mhz) signals output from DS90UB914A to 913A

what's the minimum length mismatch should we keep?

what's the impedance should we control ,signal-end 50ohms?

application as below

best regards

Hi, please check ub913a's d/s, the setup/hold time spec. is >2ns.

For ub914a, the output skew is about 0.12UI. So the variation in your case is <2.7ns.

also, pls use ub934 to replace ub914a in your case.

regards,

Steven

hello steven

thank you for your reply

why should we change 914A to 934 , 914A is NG?

we have bought 914a samples

this time the use of 914A is not for mass production ,it is only for test

can we use it

Hi,

this is our suggestion for new design. UB934 is new device with performance improvement, such as raw12 data rate, back channel noise improvement etc. so it is recommended.

if you had used ub914a, it also can be used.

best regards,

Steven
