'[PICLIST] [BUY] Atomic Clock Receiver'

Does anyone know where I can get an atomic clock receiver that I could
interface to a pic? The big problem is cost, I'm not willing to spend more
than $50 USD. If anyone could recommend one, I'd really appreciate it.

If you mean a clock that receives time via radio (WWVB), there are many.
Check out Radio Shack for their $40.00 Oregon Scientific version
http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&category%5Fname=CTLG%5F007%5F012%5F001%5F000&product%5Fid=63%2D968

or browse these search results for other options.

There are several web retailers selling these sorts of clocks as well.

BTW they already use a PIC <G>. You'll just need to tap off
and decode the recovered 60khz data stream coming from the antenna.

I tracked down a company a few months ago that make 2 different chips for
receiving the atomic clock pulses.  I am sending this before I find them
again.  I sent an email to the site below requesting help.  The company that
makes the chips does not seem to be in any search engine on the internet.
The atomic clock manufacturers all use chips from this company.


Here is the government site for the atomic clock in Colorado.  The system
was upgraded a few years ago so that within 2000 mile of the site you can
receive the signals.  Germany has its own version, as does England and
Japan.  The data sheet shows the timing pulses for each country.  The data
sheet shows how to use a ferrite bead tuned to 60khz, the tranmission
frequency.  The chip decodes the signal to interface it into a
microprocessor.

I was thinking that someone needs to design an atomic clock to RS-232 module
for the home automation industry.  I am in the lighting control industry and
most home automation systems have very poor accuracy with their internal
clocks.  This would be a great add on!  Well, there is an idea for someone
with more time on their hands than me!

Maybe someone out there can track down the manufacture. I am also going to
look for the data sheet they sent me!

Do a search on Zeit or Arcron ... they make an atomic clock with an RS-232
interface to set a PC's clock.

I have made a GPS reciever to PIC for this reason...

Careful, The format of the transmitted signals is different. A Receiver
which decodes signals transmitted by MSF will not decode the signals
transmitted from Colorado (WWV?) even though they both operate on 60kHz.

Their dedicated Receiver IC are suitable though. They are actually
manufactured by Gunter Semiconductor
http://www.gsg-asia.com/ic_data_sheet/ak2124.pdf

Temic also make (made?) chips U4223B. I believe that they are now part of
Atmel.

You will of course have to add a PIC to do the decoding.   8-)
