I understand that the micros work fine, it just seemed like you would
need a second one to discipline the OCXO because of the timing
constraints on the divider.

Hi,
Sounds like someone made a solid state Decatron,

I too have looked at the SiLabs parts. I may just have to get one of
their eval boards.
I use the SiLabs CP2102 USB-to-Serial converter in my new receiver Eval
Boards. Tiny little thing, no external components, and it also has the
ability to handle more than just RxD and TxD traffic.
Said/Didier,
There just must be something special about Philip's PLL designs. Way
back when when I was working in the underwater world we used a small
underwater range finder (sonar) that used the Philips 4046 PLL. The
Philips part was the ONLY 4046 that would meet the range and jitter
specs. We

Magnus,
I hope NO ONE is using a 4046 in any contemporary CD player designs!

There is actually two different 4046s around. One has more input gain
than the other, which can create a
Hi,
I recently used the Philips 74HCT9046A, a variant of the
4046/7046 with a charge pump on the type-II (frequency/phase)
output, in a GPS frequency standard project. However this family
tries to be all things to all people and I would like a simple
phase comparator (EXOR will do) with said

I would say that if it locks up and works, leave it alone.
The lamps last a long time. Deal with it when or if it goes.

it's normal,
After replacing the lamp you have to readjust some parameter as

I've recently traded for one of these receivers, but there's no antenna with it.
Does anyone on the list have an antenna for this unit that they'd part with?

Hi Said,
Thanks for the info, I did check the Philips (and Sparkfun) web site(s)
and I must admit the ARM chip is cheap and has impressive
specifications. With the GNU tools, I know it will work and it will fit
my homebrewer's budget :-) I used to consider $99 for a development kit
cheap, but
