[time-nuts] Motorola Oncore GPS Interface Board?

[Randy Warner]

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.


Randy

Subject: [time-nuts] Motorola Oncore GPS Interface Board?

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.
