NE/SE567

Tone decoder/phase-locked loop

403

April 15, 1992

853-0124 06456

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
