[time-nuts] rockwell gps chipset datasheet?

[Roberto Barrios]

Hi Frank,

The Rockwell 11577-11 is found in most TU-DXXX Rockwell-Jupiter GPS
receivers. I've never seen anything like a RF switch on them, but you could
have a custom or exotic one :). What they do have most times is a model
number etched or printed on the PCB. Doesn't yours have one?

You can find a few Rockwell GPS datasheets here, where you can compare yours
with the pictures: http://www.gpskit.nl/downloads-nl.htm

Hello all,

I have given a GPS receiver board from an old anti-theft system, it's
free for me to play with (and more are available if I ever figure out
if they can be useful). The board has a rockwell chipset for the GPS
part and two antenna connectors (selectable with an rf switch). Both
antennas have independent power supply, I think it's +5V, I've not yet
powered it up, I'm waiting to figure out more things about it.
Rockwell chips are R6732-13 (the one where RF signal goes) and the
bigger 11577-11. Now I haven't been able to dig any pinout at least
for the 11577-1. Anyone?

Thanks in advance
