Overview

Product details

XD567 is a universal audio decoder designed to provide a saturated transistor switch ground when there is an input signal in the passband. The circuit consists of an I and Q detector driven by a voltage controlled oscillator, which determines the center frequency of the decoder. External components are used to independently set the center frequency, bandwidth, and output delay.

Features

● Frequency range of 20:1 (adjustable with external resistors)
● Logic-compatible output with 100mA 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 adjustable centre frequency from 0.01Hz to 500kHz
