ELM446 Datasheet (ELM) - 50Hz Generator

ELM446, 50Hz Generator

The ELM446 is an 8 pin digital divider integrated circuit, that provides both 50Hz and 1Hz outputs from a common 3.58MHz NTSC colourburst crystal.

Externally, the designer need only provide the crystal and two appropriate loading capacitors, as well as a suitably bypassed power supply.
