Accurate 1 kHz Square Wave Crystal Oscillator Circuit

 Accurate 1 kHz Crystal Oscillator Circuit Diagram 1khz cd4060 hfe4060

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.

1kHz Circuit

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 213=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.

CD4060 pin configuration

CD4060 contains oscillator or astable  stage followed by a 14 stage binary counter/divider.

Above circuit works between 5v to 15v.

    I Need A Mixer Digram Possibly Build With Jrc45508

  4. Ger says:

    If I change XTAL = 27Mhz , I will have 26367Hz in pin 14 ??, thank you.

  5. Ger says:

    PIN = 15 , sorry.

  6. Kit Bates says:

    Can someone please help me produce a circuit that can be produced en masse that generates an accurate frequency of 528Hz ± 0.1Hz.

    require circuits to convert square to sine wave
