Hi team,
Below is the diagram of my customer's application.
The output signal of LMK00301 is LVPECL and the input signal of the PHY.
Customer use the phy to monitor the output clock of the LMK00301, and we found when the temperature is high, there occur the problem of frequency shift.
And we also get the input signal of the phy
Could you help me to check the matching network between the LMK00301 and PHY and give your comment to the problem
