Circuit Digital Clock by MM5369
This is
digital circuit, Pulse Generator 60HZ and TP 3.579MHZ. It use IC MM5369 – 8Pin easy use. power supply 12V.Out put Frequency 60HZ Pulse Generator. (PIN 1)
This is calibration frequency standards for digital clock circuit. When you have finished building your digital clock circuit kits, with any ICs number. But how to
which normally we will be get the standard frequency signal of AC power line 60Hz (North America the power line frequency is 60 cycles per second or 60 Hertz) that is a sine wave and then is converted with the Pulse Generator
circuit become to square wave form of 60 Hz .
In working heart of this circuit is the crystal oscillator has frequency of 3.579 MHz and MM5369AA-IC only as circuit shown in figure first.
The signal output of this
circuit will be have two frequency are 60 Hz applied to your job and 3.579 MHz to adjust frequency to work properly.
