UTE OUTPUT
(MUTE)
During the dialling sequence this push-pull output is
activated. In the pulse dialling mode, MUTE goes HIGH
prior to the dialling action and goes LOW after the last
t
idp
(interdigit pause), see Figs 11 and 12. In DTMF
dialling, MUTE goes HIGH prior to the dialling action and
goes LOW after an additional ‘holdover’ time, see
Figs 13 and 14.
This output is also activated if the device enters the
programming mode, to avoid transmitting the keys
entered.
5.1.8
DTMF
OUTPUT
(TONE)
The timing sequence for DTMF dialling is illustrated in
Figs 13 and 14. The tones generated by this TONE are
filtered by an on-chip switched capacitor filter, and active
RC low-pass filter. Therefore, the total harmonic distortion
fulfils the CEPT CS203 recommendations. An on-chip
reference voltage provides output tone levels independent
of supply voltages and temperatures. Spread among the
individual parts is extremely low.
The DC level of the TONE output measures 0.5V
DD
and
the impedance is 100
(typ.). Table 2 shows the
frequency tolerances.
The TONE output is also used to generate the ringer
melody, key entry acceptance beep, error or warning
beeps and confirmation beeps. These beeps are
generated/set in programming mode as a response to the
users action. The ringer is designed to generate
3-melodies that may be selected using the keyboard.
Table 3 shows the implemented ringer melodies.
