Accurate 1 kilohertz (1kHz) square wave frequency generator schematic

This is a simple, accurate 1 kHz (1 kilohertz) 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. CD4060 contains oscillator or astable  stage followed by a 14 stage binary counter/divider. In this circuit pulses at IC1 pin 2 (Q13) divide by 2¹³=8192. When we use 8.192MHz crystal we can get 1 kHz square wave frequency output.

8.192MHz/8192=1kHz

R1 acts as bias resistor. R2 acts as a current limiting resistor.

CD4060 oscillator features – All active components on chip, RC or crystal oscillator configuration, RC oscillator frequency of 690kHZ min. at 15V

CD4060 applications – Control counters, Timers, Frequency dividers, Time-delay circuits

Above circuit works between 5v to 15v.

UPDATE: (09/08/2018)
Please increase supply voltage between 10V to 15V, If circuit fail to oscillate.
