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 Regards, Roberto EB4EQA ---------------------------------------- Message: 1 Date: Tue, 17 Feb 2009 12:33:36 +0100 From: francesco messineo <francesco.messi...@gmail.com> Subject: [time-nuts] rockwell gps chipset datasheet? To: time-nuts@febo.com Message-ID: <d9f2bc20902170333x5d7b0a72gd935a54cf0a66...@mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 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 Frank IZ8DWF _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
