Programmable multi-tone telephone ringer

Product specification

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.

2 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.
