One-chip telephone ICs with speech,
dialler and ringer functions
UBA2050(A); UBA2051(A;C)
Notes
1.
When this level is reached at rising V
DD
, the internal reset signal is deactivated. There is no hysteresis in the
switching level, only hysteresis in the time domain.
At start-up the output has a pull-up source I
OH2
for detection of the resistor options. After initializing the output pull-up
source will be I
OH1
.
MDY/TONE has three modes:
a) In speech mode or DTMF mode: 0.5V
DD
output.
b) In ringer mode: push-pull output stage.
c) In standby mode: high-impedance output.
Related to the low group frequency component (CEPT CS203 compatible).
In the event of a valid ringer signal present at pin CE/FDI.
