12/27/2023 0 Comments Crystal circuit racer![]() However, If you think that this circuit is not good enough for you. We use a 3.579545 MHz crystal then measure frequency output show on LED display highly accurate. The tree inverters gate are biased into their linear regions by R1 to R4, and the crystal provides the feedback. This is a simple and cheap crystal oscillator circuit, that we use a few parts comprises a TTL digital number SN7404 or SN74LS04 (Package contains six inverters), four resistors and a crystal. When we need a highly accurate, it uses the crystal frequency control better. However, when studying the TTL IC., Which is the basis of a digital circuit that everyone should learn it.Īlthough it can be tricky about the power supply to 5V fixed and high current consumption. And 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.

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. ![]()
