Tone decoder/phase-locked loop
Product specification
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
