Hi,

for a very cost sensitive application including a DCF77 time signal
detection I found the 16F639 with an analog front end, which is usually use=
d
to detect 125KHz signals. After having a first look at the data sheet it
should also work for 77,5KHz, but I wanted to know if anybody else did this
before successfully.

I know, usually a complete DCF77 module (including all this AGC stuff) with
digital output is connected to a PIC but if it works with just a cheap
ferrite coil it would help to bring down the cost.

Any help or ideas?

Thanks and best regards

Peter
