Accurate 1 kilohertz square wave frequency generator schematic
This is a simple, accurate 1 kHz square wave crystal oscillator circuit using frequency divider IC and crystal.
| PARTS LIST |
| C1 |
22pF ceramic |
| C2 |
22pF ceramic |
| C3 |
0.1µF mylar |
| R1 |
10MΩ ¼W |
| R2 |
220Ω 100Ω ¼W (R2 change to 100Ω because sometime circuit fail to oscillate) |
| XTAL |
8.192MHz crystal |
| IC1 |
CD4060 |
Our circuit uses a CD4060 ripple carry binary counter to divide the
crystal frequency. In this circuit pulses at IC1 pin 2 (Q13) divide by 2
13=8192. When we use 8.192MHz crystal we can get 1kHz square wave frequency output.
8.192MHz/8192=1kHz
R1 acts as bias resistor. R2 acts as a current limiting resistor.Crystal Oscillator, 1 kHz Square Wave
