Jason, If you need something quick we can probably sell you a couple of our SynPaQ/III motherboards. These boards are used in our SynPaQ/III GPS receivers. They probably have more features than you need, but they work quite well. All I/O is buffered and protected from EMI. The 1PPS is buffered with a 74ACT04 and drives 50 ohms easily with a 8-10ns risetime.
It may not be the least expensive option, but it can be delivered immediately.

I have a couple of the Motorola Oncore UT+ boards, right now I just cobbled an interface to my zodiac dev kit to use one, but I was looking for a more permanent interface board. Something similar to the one TAPR used to supply: http://www.tapr.org/gps_vpib.html Is there anyone out there that happens to currently have some nice PCBs (not necessarily populated with the components), or am I going solo on this one? If there isn't a (cheap) supply of them anywhere, if I draw up and have some PCBs produced (there are various places online I've seen that can make small quantities) would anyone else be interested in purchasing? Before saying "Why don't you get xxx GPS instead?"... I have my reasons for wanting to use the Motorola. :P I contacted the original author that made the above mentioned board and he's going to send me a PDF of his design. If I make my own I'll probably improve on it some adding at least some additional buffered PPS outputs. _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
