GENERAL DESCRIPTION
The UAA2062 is a BiCMOS integrated circuit that
performs all functions from the antenna to the
microcontroller for reception and transmission for both the
base station and the handset in a cordless telephone.
This IC integrates most of the functions required for a
cordless telephone into a single integrated circuit. The
implemented programming enables the device to be used
for the CT0 standard in many countries. Additionally, the
implemented programming significantly reduces the
amount of external components, board space
requirements and external adjustments.
PACKAGE
Microphone amplifier
Compressor
Programmable TX gain.
3-wire serial interface.
Voltage regulator to supply internal PLLs and the
microcontroller
Programmable low-battery detector time multiplexed
with RSSI carrier detector.
World-wide analog cordless telephone set (CT0).
