Introduction

The XD567 and XL567 are general-purpose speech decoders designed to switch saturating transistors to ground when an input signal is present in the passband. The circuits contain I and Q detectors driven by a voltage controlled oscillator which determines the centre frequency of the decoder. External components are used to independently set the centre frequency, bandwidth and output delay.

Features

• Frequency range of 20:1 (adjustable with external resistors)
• Logic-compatible output with 100 mA sink current capability
• Bandwidth adjustable from 0% to 14%
• Effective suppression of out-of-band signals and noise
• Resistant to spurious signal interference
• Highly stable centre frequency
• Centre frequency adjustable from 0.01Hz to 500kHz
