Other Parts Discussed in Thread: CDCE62005, CDCM6208

Hi,

I want to use one CDCE62005 clock generator , iam using 25Mhz Crystal as input, i require 4 different clocks 100Mhz, 312.5mHZ,312.5Mhz & 166mHZ.

Is it possible to generate 312.5Mhz with 25Mhz Crystal. If not possible suggest alternate clock generator.

Regards,

Srinivasaprasad.

    Hi Srinivasaprasad,

    It does not seem that this frequency plan is obtainable using the CDCE62005. Do you have specific jitter or ppm accuracy?

    The CDCM6208 is able to realize this frequency plan utilizing fractional dividers.
