DS90UB954-Q1: CMLOUT eye width

Part Number:DS90UB954-Q1

Hi team,

We are checking CMLOUT for debug.

It is connected to 953 in synchronous mode, and 25 MHz refclk is input.

So, the data rate of forward channel is 4Gbps.

We are using CSI input with the 953 pattern generator.

I monitored CMLOUT in this state.

The jitter was small and opening eye is clean, but the eye width(1UI) is about 700 ps unlike expected.

I think that speed of CMLOUT is same as RX input.

Is it correct?

How long is correct for 1UI in our usage?

Also, please tell me how to calculate the ideal 1 UI.

Best regards,

Tomoaki Yoshida
