SN75DPHY440SS: DAxPN and DBxP/N impedance requirement

Part Number: SN75DPHY440SS


Hi All,

The D/S of the SN75DPHY440SS mention that the DAXP/N &DBXP/N pairs differential impedance should be 100ohm with +/-15%.

May I know the impact if the impedance is not in this range, maybe 80ohm or even lower?

Please kindly share your comment with me.

Thank you.

BR
