DP83620: 100BASE-FX receive interface from AC coupled CML optics

Jonathan Geronga

Part Number: DP83620

Hi Team,

Our customer would like to know in the 100BaseFX mode, what the receiver common mode voltage and min/max differential swing is for the DP83620?
They have an application where they are ac coupled to an optical module driving CML with ~ 450mV single end swing.
Is there any input jitter or pulse symmetry requirements on the receiver in 100BaseFX mode?

Please let me know if you have questions with the customer.

Thanks,

Jonathan

Hi Jonathan,

If the optical module is 100BaseFX compliant, there should be no issues regarding common mode voltage swing. Please let me know if you have any further questions. Else, I will close this thread.

Thank you,

Nikhil
