NE567数据手册集成电路（IC）的电信规格书PDF

描述 Description

DESCRIPTION
The NE/SE567 tone and frequency decoder is a highly stable phase-locked loop with synchronous AM lock detection and power output circuitry. Its primary function is to drive a load whenever a sustained frequency within its detection band is present at the self-biased input. The bandwidth center frequency and output delay are independently determined by means of four external components.FEATURES
• Wide frequency range (.01Hz to 500kHz)
• High stability of center frequency
• Independently controllable bandwidth (up to 14%)
• High out-band signal and noise rejection
• Logic-compatible output with 100mA current sinking capability
• Inherent immunity to false signals
• Frequency adjustment over a 20-to-1 range with an external resistor
• Military processing availableAPPLICATIONS
• Touch-Tone decoding
• Carrier current remote controls
• Ultrasonic controls (remote TV, etc.)
• Communications paging
• Frequency monitoring and control
• Wireless intercom
• Precision oscillator
