The calendar clock is punctual, easily adjusted, clear at night and easily made.Working principleThe core of the circuit is a PMOS mass integrated circuit LM8364. 4-pin is the selective terminal of 12/24 h, and the high LEV is 24h system. When 6-pin is suspended, the 60Hz time based signals are input from 7-pin, and when receiving the high LEV, the 50Hz time based signal should be input from 7-pin.
