The PCD3332-2, PCD3332-3 and PCD3332-S are mixed-mode multistandard repertory dialler/ringer ICs, fabricated in a low threshold voltage CMOS technology. Dial parameters of these ICs can be set by diode options to meet the specific requirements for various countries.
The on-chip tone generators are used for DTMF dialling and ringer melody generation. A discriminator input enables the tone output only if a correct ringer frequency is applied. Repertory numbers of up to 32 digits can be stored, with maximum storage of 250 digits.
