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
