ELM440規(guī)格書詳情
描述 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. Internal oscillator circuits then use this reference frequency to precisely derive a stable 60Hz signal. This signal is then further divided to provide a 1Hz output.
特性 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
? Uses a standard 3.58MHz crystal for the time reference if there is no sync input
? High current drive outputs - up to 25 mA
Applications
? Stable 60Hz and 1Hz reference sources
? Master oscillator for clock / timekeeping functions
? DC powered backup 60Hz reference signal
