DP83620: DP83630 100BASE-FX mode PECL PHY input thresholds

Dylan Loughnan
Prodigy 50 points
Part Number: DP83620

We are working on an application with the DP83620 in 100BASE-FX mode.  We would like to interface with an, AC coupled, LVDS transceiver.  What are the VIL (max) and VIH (min) threshold values for the PHY (receiver) in 100BASE-FX mode (RD+/RD-)?

I could not seem to find the information in the datasheet.

Thanks for your help.

    Hi Dylan,

    We unfortunately do not have VIH and VIL data that we can share.

    The FO port was validated with the LVPECL transceiver shown on the reference design: the Avago/Broadcomm AFBR-5803Z.

    If your electrical specs match that transceiver, that would be the highest confidence for your design.

    Best Regards,
