Hi, I have a GPS box based on the Sirf GPS1 chipset.
I'd like to tap in and get a stable clock signal out of it.
Rumors ar there's a 1pps, a 50Hz, and maybe other stable frequencies in
there.
I probed around with a scope but didnt see anything too stable, except
something around 1.1MHz.
Does anybody have the pinout of the GPS1 chip, or know which pins have good
cklocks on them?
www.sirf.com doesnt seem to have anything too techincal like, a chip data
sheet or anything useful like that.
Thanks,
George
