Tone decoder/phase-locked loop	NE/SE567

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
