ELM446 Description
The ELM446 is an 8 pin digital divider integrated circuit, that provides both 50Hz and 1Hz outputs from a mon 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. Internal oscillator circuits then use this reference frequency to precisely derive a stable 50Hz signal.
