TVP5151 crystal selection

Other Parts Discussed in Thread: TVP5151

Hi,

is there any specific ESR requirement for a crystal for TVP5151?
The datasheet states just the frequency and ppm requirements.

Thanks
Massimo

    Massimo,

    ESR is not as big a concern as frequency, ppm, and CLoad matching.  ESR of fundamental crystals typically decreases as operating frequency increases.  ESR of various 27MHz crystals we have used were specifed in the 30-50-ohm range.
