Overview
XR·567A Precision Tone Decoder GENERAL DESCRIPTION The XR-567A provides all the necessary circuitry for constructing a variety of tone detectors and frequency decoders.
Phase-locked loop circuit techniques are used to provide operation from 0.
01 Hz tp 500 kHz.
The circuit also features an input preamp, a high-current logic output, and programmable output delay.
The XR-567A, available in an a-Pin DIL package, is designed to offer improved frequency accuracy and drift characteristics over the standard industry 567.
These changes offer improved overall circuit performance, while reducing initial circuit adjustments.
