Key Specifications
Package: 405
Length: 10.287 mm
Description
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. Externally, the designer need only provide the crystal and two appropriate loading capacitors, as well as a suitably bypassed power supply.
Key Features
- 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
