DS90UB948-Q1: CMLOUTP/N range of 948 and 928

Betty Guo

Part Number: DS90UB948-Q1

Hi team

what's the CMLOUTP/N range of 948 and 928? in the datasheet, only show the typical value is 360mV. what's the maximum and minimum ?

thank you

Hi Betty,

We have only characterized the typical value for CMLOUT, and don't do any additional screening, characterization, etc past the 360mV typical statement. This is part of the reason why CMLOUT/eye monitoring isn't the preferred pass/fail condition or are eye masks provided since sometimes there is variance in the signal amplitude.

Regards,

Logan

Hi Logan,

can we adjust the CMLOUT amplitude? customer measured the CMLOUT, the amplitude is 720mV, which result the eye diagram test fail.

Hi Betty,

CMLOUT amplitude is not adjustable.

Each CMLOUT_P/N amplitude is 360mV, therefore a total differential output voltage of 720mV is expected.

Logan
