Other Parts Discussed in Thread: AM69A, CDCE6214
I am going to to use PCIe GEN3 in AM69A. In the design I will use a clock generator and a clock multiplier for ref clocks.
But at this point I have a question.
The clock generator will generate ref clks with 1.8V output voltage . However clock multiplier output voltages are 3.3v and AM69A serdes voltages are 1.8V also.
In this diagram can I directly connect ref clks to each other. Or do I have to use ac coupling caps ?
Could you please give information?
