DS90UB954-Q1: 954 &933

Part Number: DS90UB954-Q1

Hi,

Will both LOCK and PASS output high levels if link is ok?Our side is now LOCK will output the high level, but the PASS foot will output a square wave of high frequency from the oscilloscope, what is the possible cause of this situation.

What is the peak value of CSI_CLK output of 954? We can see the waveform here, but the peak voltage is only about 200mV, and the data port can have 1.2v. Is this output state normal?

Thanks!

    Hello Neal,

    LOCK indicates if you have an input/communication between SER and DES. But PASS can be configured to go high once you have active data.

    Can you send me register dump from the 954, I believe you have some issue with the input signal/settings.
