描述 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.

特性 Features

• Low power CMOS design

• Wide supply range - 3.0 to 5.5 volt operation

• 3.58MHz crystal controlled operation

• Generates both 50Hz and 1Hz references

• Low parts count

• Complementary 50Hz outputs

• High current drive outputs - up to 25 mA

Applications

• Stable 50Hz reference

• Master oscillator for clock / timekeeping functions

• Decimal based time reference for easier period calculations
