Circuit Crystal Oscillator
I like the
circuit, because it is good and enjoy. It just the signal status “1″ and “0″ only. And frequency generator is circuit that I like.
However, when studying the TTL
IC., Which is the basis of a digital circuit that everyone should learn it.
Although it can be tricky about power supply to 5V fixed and high current consumption. It can be used with very high frequency. When we need a high accurate, it uses the crystal frequency control better.
This are simple and cheap crystal oscillator circuit, that we use a few parts comprises a TTL digital number SN7404 (Package contains six inverters), four resistors and a crystal.
The tree inverters gate are biased into their linear regions by R1 to R4, and the crystal provides the feedback.
