The 33k/150 were chosen to get CMOS compatible output. The circuit will
oscillate with much higher values for each.

The two 100p might be slightly too high for the 18p crystal I'm using,
but I didn't tune those carefully because I want to pull the crystal
slightly, and in my actual circuit the grounded leg of the crystal is
actually in series with a variable capacitance to tune the VCXO.

Hi Ben, Thanks. What is the nominal setting of the cap in series with the
crystal? 18pf or so?

Do you have any info on the crystal, such as make and model?

Or any idea what the series resistance might be?

Would you like me to post the results to my web site?

Regards,

Mike Monett
