Other Parts Discussed in Thread: CDCE62002

Hi,


I am using CDCE62002 as a clock synthesizer. I am using PECL input as Xtal oscillator. Getting PECL Output. Input frequency 125MHz and Ouput frequency 250MHz and 62.5MHz. I am facing some problem while choosing the termination method. How should I terminate the signal? AC Coupled or DC? What are the parameters for various types of  termination?

Thanks in advance. :)

Sincerely,

Adib
