GENERAL DESCRIPTION
The PCD3311C and PCD3312C are single-chip silicon gate CMOS integrated circuits. They are intended principally for use in telephone sets to provide the dual-tone multi-frequency (DTMF) combinations required for tone dialling systems. The various audio output frequencies are generated from an on-chip 3.58 MHz quartz crystal-controlled oscillator. A separate crystal is used, and a separate microcontroller is required to control the devices.
FEATURES
• DTMF, modem and musical tone generation
• Stabilized output voltage level
• Low output distortion with on-chip filtering conforming to CEPT recommendations
• Latched inputs for data bus applications
• I2C-bus compatible
• Selection of parallel or serial (I2C-bus) data input (PCD3311C).
