PSB 21373

Overview
The SCOUT
-DX integrates all necessary functions for the completion of a cost effective
™
digital voice terminal solution.
®
The SCOUT-DX combines the functionality of the ARCOFI
-SP PSB 2163 (Audio
1)
Ringing Codec Filter with Speakerphone) and a two wire line interface
on a single chip.
The SCOUT-DX is suited for the use in basic PBX voice terminals just as, in combination
®
with an additional device on the modular IOM
-2 interface, in high end featurephones
e.g. with acoustic echo cancellation.
The transceiver implements the subscriber access functions for a digital terminal to be
connected to the two wire line interface. It covers complete layer-1 and basic layer-2
functions for digital terminals.
The codec performs encoding, decoding, filtering functions and tone generation (ringing,
audible feedback tones and DTMF signal). An analog front end offers three analog inputs
and two analog outputs with programmable amplifiers.
The IOM-2 interface allows a modular design with functional extensions (e.g. acoustic
echo cancellation, modem extension) by connecting other voice/data devices to the
SCOUT-DX.
A serial microcontroller interface (SCI) is supported.
The SCOUT-DX is a CMOS device offered in a P-MQFP-44 package and operates with
a 5 V supply.
