Product specification
Programmable multi-tone telephone ringer
PCD3360
1
FEATURES
Output signals for electro-dynamic transducer
(loudspeaker) or for piezo-electric transducer (PXE)
7 basic output frequencies (tones) and a pause
4 selectable tone sequences
4 selectable repetition rates
3 selectable impedance settings
3-step automatic swell
Delta-modulated output signal that approximates a
sinewave
Input ringing frequency discriminator with selectable
upper and lower frequency limits
Output for optical signal
Customized tone sequences, impedance settings and
automatic swell levels are mask programmable.

GENERAL DESCRIPTION
The PCD3360 is a CMOS integrated circuit, designed to
replace the electro-mechanical bell in telephone sets.
It meets most postal requirements, with selectivity of
output tone sequences and input ringer frequencies.
Output signals for a loudspeaker or for a piezo-electric
(PXE) transducer are provided. No audio transformer is
required since the loudspeaker is driven in class D.
