Product specification

GENERAL DESCRIPTION
The ICs UBA2050, UBA2050A, UBA2051, UBA2051A and
UBA2051C contain all the functions needed to build a fully
electronic telephone set.
In many places in the text, figures and tables, the
description is not applicable for all the five types, but only
for one or two or for a combination. These combinations
will be referred to by means of short denotations as given
in Table 1.

all five types
The devices incorporate a speech/transmission part, a
dialler part and a ringer part. By offering a wide range of
possible adaptations for each part, the UBA205xx
applications can be easily adapted to meet different
requirements.
Speech/transmission part
The speech/transmission part performs all transmission
and line interface functions required in fully electronic
telephone sets. It performs electronic switching between
transmission and dialling. The IC operates at a DC voltage
down to 1.45 V (with reduced performance) to facilitate the
use of telephone sets connected in parallel.
When the line current is high enough, a fixed amount of
current is derived from pin LN in order to create a supply
point at pin VDD. The voltage at pin VDD is regulated at
3.3 V to supply the dialler and ringer parts and peripheral
circuits.
Dialler part
The dialler and ringer parts of the IC are responsible for
the system control, system settings and the generation
and detection of various signals.
The dialler offers a 32-digit last number redial function.
The UBA2051x offers in addition 13 memories
(3 direct + 10 indirect) of 21 digits.
During pulse dialling the DMO output of the UBA205x can
be used to decrease the line voltage. During tone dialling
the LED output of the UBA205xA is used to indicate DTMF
dialling. A keytone is available if a valid key is pressed for
the types UBA2050x and UBA2051C.
Ringer part
The ringer part offers a discriminator input which enables
the MDY/TONE output as soon as a valid ring frequency is
detected. It offers a choice of 4 different 3-tone melodies
and a 4-level volume control, both programmable via the
keyboard. An external very low cost ringer output stage for
a buzzer is needed. Stabilized supply (VDD) during ringer
mode for dialler and ringer part is included.
