Hello all,
I am building a 1hz clock using a 32.768khz crystal, 4060IC, and a 4027IC.
I have built the circuit twice on a bread board driving it with a 9v battery and it works. I also have built the circuit 4 times on a circuit board with no luck. My last attempt is used the exact layout as in the schematic, which I got from hackers bench(crystal controlled 1hz based time clock).
I have no clue what is wrong. I am in desperate need of help and would greatly appreciate any information.
The component values are as follows:
LH IC=4060
RH IC=4027
R1=330KOHM
R2=6.8MOHM
R3=6.8MOHM
C1=33pf
C2=33pf
Y1=32.768KHZ
