Fig.1 FX118 Duplex Frequency Inverter

Brief Description

The FX118 is a low-power, full-duplex frequency

inverter available to provide voice privacy for cordless

telephone systems by mixing the incoming audio with an

internally produced carrier frequency (3.3kHz).

The frequency stability of the FX118 is achieved by an

on-chip oscillator employing an external 4.433619MHz

Xtal or clock input to produce the common carrier

frequency and the sampling clocks for the switched

capacitor low and bandpass filters.

This chip contains two completely separate audio

channels (C1 and C2) each comprising a “component-

adjustable” input amplifier, a 10th-order lowpass filter, a

balanced modulator and a 14th-order bandpass filter

output.

This microcircuit has a low power requirement of 3.0

volts (min.) and is encapsulated in either 16-pin DIL or

small outline SMD (S.O.I.C.) plastic packages both of

which are of a physical size suitable for either base or

handset type telephone instruments as well as battery-

portable and mobile communications systems.

The on-chip modulation process has the properties of

high baseband and carrier frequency rejection which

when combined with high-order output filtering,

produces a high-quality recovered voiceband audio.
