Hi team.

For output Eye Width/Heigh of 924, the spec. just show the typ. value (0.4UI / 300mV) as shown the below capture. What is the minimum value for these two parameters? Thank you.

Best regards,

Hello Ansel,

We do not specify a minimum value for CMLOUT since it is general debugging tool which is reconstructing the forward channel eye. It does not give a 100% accurate representation of the signal recovery within the deserializer so it is recommended to use the Margin Analysis Program to qualify the forward channel link margin:
