12/24/2022 0 Comments Osculator for ceramic resonatorAnd the frequency generator is a circuit that I like. It just the signal status “1” and “0” only. I like the TTL crystal oscillator circuit. Universal PCB board Testing Crystal oscillator using TTL 74LS04 The components layout of this circuit The components list You can make easily this circuit on the universal PCB as Figure. And protect Interference that may occur to the circuit.įor IC1 may be LS, HC or HCT types. Then, C2 pulls a high frequency that contamination from power supply to ground. Related: 7805 voltage regulator IC: Pinout, Datasheet and example circuits There are capacitor C1 and C3 filter current to smooth. Using DCV supply of 9-12 volts comes to DC regulator IC2-78L05. This circuit uses a low current consumption and constant power supply of 5V. When compared with the common oscillators. Which affects the capacity within the crystal and making frequency tolerances.īut it has very less value. Because of its temperature changes while working. Though the stability of this output frequency has slight defects. They can generate the output constant frequency of 1MHz to 10 MHz. Working with two inverter gate within IC1.Both resistors R1 and R2 must be the same resistance. To working instead of the RC network circuit. They match the crystal and two resistors. In the circuit below is the simple oscillator that generates the square wave or DC pulse. How Crystal Oscillator circuit Works Simple crystal oscillator 1-10MHz using inverter gate
