DS90UB954-Q1: eye, cmlout, csi, UI

Part Number: DS90UB954-Q1

Hi~

I need help to understanding 1 unit interval of DS90UB954-Q1.

DS90UB954 max rate is 1664MBps and 832MHz at that time. to check Eye window, 1UI=1/(CSI_freq/64) is described in datasheet.

And then, 1UI=1/(832MHz/64)=7.69*e-8, it means 1 UI EW freq is just 13MHz,,, am I right?

Deserializer 13MHz looks too low and I need help to understanding 1 UI in time and freq domain.

Thanks.
