NE567 - Tone decoder/phase-locked loop

General 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.

Key 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 F Package OUTPUT 1 C3 2 NC 3 C2 4 INPUT 5 NC 6 VCC 7 TOP VIEW 14 GND 13 NC 12 NC 11 R1C1 10 R1 9 8.

Philips Semiconductors Linear Products Product specification 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.
