10-20 MHz low power PLL
10-20 MHz low power PLL
(OP)
I'm looking for a low power PLL to generate a couple different clock frequencies from a single reference. Needs to be fractional N. Need 12 an 16.384MHZ am having trouble finding anything suitable. Any recommendations?

etc. Every omitted data may cost a LOT...

There are plenty of low power synthesizer chips at VHF,UHF and microwave frequencies but am having trouble finding anything integrated in this range.

Fractional-N may not be the simplest -- e.g. once I have
made a frequency divider (by 625) with 4 transistors and
a few discrete parts...
Do you need coherency only to avoid metastability ?
Is your application all digital ? What does the analog
do?

National LMX2350. It wasn't initially obvious because this is actually a dual part. One half supports microwave frequencies but it has an aux half that only uses 1 mA that will work in the frequency range I need.
