I have done some transient simulations with the HMC7043 IBIS model and the LVPECL AC-Coupling technology for a SYSREF (around 10MHz) and CLOCK (around 800MHz) signals.
The results show a differential output power around 980mV whereas the datasheet indicates around 1.8V.
I also had to manually implement the termination network because the term4494 didn’t affect at all my signal.
My IBIS file was configure with the following parameters :
Have you got recommendations for me to get a well-functioning channel matching with the values of the datasheet, please ?
