DS90UB933-Q1: criteria of the eye width/height to pass signal quality test

Rory Wu

Part Number: DS90UB933-Q1

Hi team,

My customer asked about that how to check whether the eye width/height can pass signal quality test of DS90UB933-Q1? They tested the LVDS output of 933. Many thanks.

Hi Rory,

We provide the jitter spec in the datasheet that can be used to determine the quality of the input PCLK or external OSC. Please refer to the Electrical Characteristics table in the datasheet for that info.

Hi Mandeep,

It is not PCLK or external OSC quality, customer want to know the criteria of video signal quality like 933 LVDS output, similar as below 954 CMOUT requirement: 0.45UI or 112.5ps. Thanks.
