NE567D中文资料飞利浦数据手册PDF规格书

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 available

APPLICATIONS

• Touch-Tone decoding

• Carrier current remote controls

• Ultrasonic controls (remote TV, etc.)

• Communications paging

• Frequency monitoring and control

• Wireless intercom

• Precision oscillator
