Which Quarz-Type - Vendor, works best with the LPC210x? - Markus Meng - Feb 1 8:10:00 2005

Hi all,

I intend to use a "14.7456MHz HC49US/THT" type of quarz for the
oscillator. However with 2 x 39 PF caps, it seems to be hard to
find an appropriate type, that works best with the LPC210x.

Could somebody give me a hint which type works best in his
application - Vendor Number?

Best Regards
Markus

Hi,

39pF caps sounds awfully large in my ears... try 15pF

Regards
Lasse

That is what Philips specifies; they have a table with suggested values for
different frequencies in the documentation somewhere.
