Part Number: CDCE913

Hello,

I am not able to select perfect crystal for CDCE913 chip. Selection guide suggest for below feature, Most of crystal datasheet not showing Pullability ratio or pulling range,

VCXO Application Guideline for CDCE(L)9xx Family suggest for below recommended crystal but none of them available in digikey, Please help me to select crystal for same. 

Thanks,

Pankaj

    Hi Pankaj,

    The datasheet crystal specifications are recommended but not absolutely required- for example pullability ratio or pulling range recommendations do not have to be followed but will affect how the device frequency can be tuned in VCXO mode. If you are only concerned with using the device as a clock generator these specifications are not critical.

    Refer to the below app note to help select an appropriate crystal depending on your application:
