The PCD3360 is a CMOS integrated circuit, designed to replace the electro-mechanical bell in telephone sets. PCD3360 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.
