Bueno:

I just hit a snag between a resonator mfg and an RFIC mfg and decided to grab
some rfPIC12F675F and rfRXD0402 chips in case I can't resolve the aforementioned
snag to my customer's (and my) satisfaction.

Before I head down the garden path and run into more problems, I'd like to query the
list members regarding ANY and ALL things - good, bad, caveats - about these
rfPIC's.

I didn't see any pricing on these in the products section. I thought MC had a
"budgetary pricing" column. Maybe that was the RFIC mfg. I haven't dealt with MC
directly yet. I'll need to source chips for the 250 Tx and 1250 or so Rx chips. That's
my customers plan for the initial production run.

I'm doing a 433.92 MHz short range ASK  (15-30m) link. I can get by with 2400 baud
or less so no prolem there. I only need to send an ID code to distinguish between
real signal and interference.

It's nothing more than a garage door opener, really. No need for Keeloq tech.

I'll be hitting the spec sheets, but if anyone has used these things, please share your
experiences.

Who supplied your XTALs and or ceramic resonators?

Rx I originally selected operates in sweep mode and a cheap ceramic worked until it
was discontinued. And I went through ALL the ANs.

Anyone know of any sliding correlator code out there to sync the ID code if the clocks
get out of whack?

I got a google first hit on PIC sliding correlator. Might work.

I can't think of anything else right now.

TIA,
Mike
