As shown in the figure for the 60Hz time base generation circuit. In many occasions, 60Hz has become a reference frequency, such as electronic clocks, timers, controllers, etc., are designed to use 60Hz as its working reference signal. Therefore, an independent 60Hz signal source is often required to be suitable for various circuits that are portable or battery-powered and for testing and development. This circuit is formed by the integrated circuit MM5369 time base generator. The device requires an external crystal, which is cut at the standard 3.579545MHz color TV "color sync signal" frequency. The output of the circuit is two frequencies of 60Hz and 3.58MHz. With the help of 5-50pF variable capacitors, the circuit can output the correct frequency. This frequency can be monitored with a frequency meter or similar instrument.
