Thanks for your replies, I found some example using serach with "counter" and "frequency"
I must explain now with more details
I don't need to generate a 1hz signal

I need to divide the signal from a 10 mhz VCXO(variable oscillator depending a control voltage)
the well know solution is to use 4 IC like 74LS390 .. too big for me ...i term of placement

That why I am looking for a newer system (example OCXO signal will become the PIC crystal and
I must find "something" to count up to 10.000.000 pulses , I know that we are working with Words
each time the word register is full, I will add 1 in a second register (up to 152 times) remaining
is 38680 ....
may be I am "outside my shoes ...." French expression ...

this 1hz signal (from VCXO) will be compared with a GPS signal (called 1 pps) this GPS is one of
the best reference to get the lowest PPM deviation

output from the comparator will be injected to the VCXO, this is in fact a PLL system !

all the PLL integrated circuits I know, don't have the internal divider up to 10 millions
I know that I can put a prescaler between the OCXO to feed the PIC but if can avoid it
it will be great !

hope my "spannish writing" is enough clear
