I believe the Western Electric D1 channel bank was the first and the
European standard came along later. Then came the D2, the D3 and
finally the D4 when integrated codecs finally came to be and it was
practical to get rid of the common codec and do it channel by channel.
I have tried to
I am working on a PLL design that uses the Lattice MX02-256 for the
dividers and XOR phase detector. I have not made any measurements on it
yet but will report back when it happens.

It looks like the winding stem is the GPS antenna? If that is the
case, then it could get calibrated when ever it can see some satellites
and sit still for awhile. The next thing it needs is solar cells to
recharge the battery. The WWVB watches are doing that now.

additional precautions that might warrant. I am
also considering making a sine wave output and maybe other frequencies.

I filter an output of an high powered 5V buffer. What I hear is a
simple passive low pass filter will do. That being the case, I may put
them on all the outputs and make it a jumper option. The other project

I am working on a small clock distributor and wanted to get some ideas
on what works best for 10MHz and 1PPS driver circuits. I remember
sifting through the archives a year or so ago and tripped on some
discussion of this but I can't find it anymore.
