[time-nuts] NavSync CW12 and CW25

[Ed Palmer]

Has anyone worked with the NavSync CW12 GPS board or the CW25 module 
that its based on?  It's been mentioned a few times on this mailing 
list, but not really evaluated or discussed to death. :-)

I'm looking for a new GPS board and this one looks quite interesting.  
It's main feature is a programmable 10 Hz to 10 MHz oscillator that's 
phase-locked to the 1 PPS output.  They're both available at the same 
time (on different pins).

The user manual isn't online, but I asked them via email and got a copy 
with no problem.  The datasheets and product briefs are available at:

I see that they're not suggesting that this little module is a 
full-blown GPSDO.  This app note talks about it.

The prices are CW12 - $89, CW25 - $64

I have no relationship to Navsync or any reseller.  I'm just a potential 
customer.

Thanks,
