Overview

ELM446 50Hz Generator Description 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.
Internal oscillator circuits then use this reference frequency to precisely derive a stable 50Hz signal.
For convenience, a complementary 50Hz signal is also provided.
This signal is then further divided to provide a 1Hz signal output.
A reset input is provided to restart the internal counters, if desired.
An active low signal on this pin will also force all of the outputs to ...
