Hi,
I am using 3.3V LVDS output of 125MHz from LMK00301A. This output is given as an input to Ethernet QSGMII PHY 88E1548's REFCLKP/N inputs.
I have used 0.01uF caps as AC coupling caps and there is a 100 ohm differential termination at receiver.
Signal integrity simulation snapshots are attached. What is the recommended termination scheme for connecting 3.3V LVDS output to 1.8V LVDS rated input?
thanks.
