Datasheet Summary
XR- 567
Monolithic Tone Decoder
GENERAL DESCRIPTION
The XR-567 is a monolithic phase-locked loop system designed for general purpose tone and frequency decoding. The circuit operates over a wide frequency band of 0.01 Hz to 500 kHz and contains a logic patible output which can sink up to 100 milliamps of load current. The bandwidth, center frequency, and output delay are independently determined by the selection of four external ponents.
