Schematic Rise

This circuit Diagram Need a 50Hz pulse. The oscillator circuit only offer the IC ELM446, crystal and 2 acceptable loading capacitors.

The IC ELM446 is an 8 pin digital divider integrated circuit, that gives each 50Hz and 1Hz outputs from a typical 3. 58MHz NTSC colourburst crystal. Externally, the designer need only offer the crystal and 2 acceptable loading capacitors, also as a suitably bypassed power supply. Internal Oscillator circuits then use this reference frequency to exactly derive a stable 50Hz signal. For convenience, a complementary 50Hz signal is additionally provided. This signal is then any divided to produce a 1Hz signal output. By ELM Electronics.
