AN6448NFBP
Speech Network IC Incorporating Cross-Point Switch
s Overview
The AN6448NFBP is a speech network IC suitable for multi-
function cordless telephones. It incorporates a cross-point
switch controlled by serial input. It allows speech path switch-
ing and mixing, and provides for three- or four-person commu-
nication and other sophisticated functions. It also incorporates
REC/PLAY amplifiers with VOX circuits.
s Features
The speech block can operate on line voltage, with no exter-
nal power supply, and is operational even during a commer-
cial power failure.
Incorporates auto. PAD, dial mute, DC voltage regulation,
and other basic speech functions.
The cross-point switch can be operated independently.
Each output of the cross-point switch can correspond to mul-
tiple inputs, allowing three-or four-person communication.
The REC/PLAY amplifiers incorporate ALC and VOX circuits.
Receiver volume can be increased by 6 dB or 9 dB.
