The ELM440 is an 8 pin digital divider integrated circuit, that provides both 60Hz and 1Hz outputs from a common 3.58MHz NTSC colourburst crystal.

Low power CMOS design.
Wide supply range - 3.0 to 5.5 volt operation.
Generates both 60Hz and 1Hz references.
Automatically synchronizes to the line frequency for long term stability, when it’s available.
Uses a standard 3.58MHz crystal for the time reference if there is no sync input.
High current drive outputs - up to 25 mA Connection Diagram PDIP and SOIC (top view) VDD XT1 XT2 reset 1 2 3 4 8 7 6 5 VSS 60Hz 1Hz sync.
