AN6472NFBP
Cordless Telephone Speech Network IC Incorporating
Cross-Point Switch
s Overview
The AN6472NFBP is a speech network IC which
includes a receiver noise reducing function and is most
suitable for quality cordless telephones. It incorporates a
cross-point switch controlled by serial input. It allows
speech path switching and mixing, and provides for
three- or four-person communication and other sophisti-
cated functions. It also incorporates REC/PLAY amplifiers
with VOX circuits.
s Features
• The speech block can operate on line voltage, with no
external power supply, and is operational even during a
commercial power failure.
• Incorporates a receiver noise reducing function to
improve the handset's howling margin.
• Incorporates auto. PAD, dial mute, DC voltage regula-
tion, and other basic speech functions.
• The cross-point switch can be operated independently.
• Each output of the cross-point switch can correspond to
multiple inputs, allowing three- or four-person commu-
nication.
• The REC/PLAY amplifiers incorporate ALC and VOX
circuits.
• Receiver volume can be increased by 6 dB or 9 dB.
