Product Summary
The PCD3311CT is a single-chip silicon gate CMOS integrated circuit. The PCD3311CT is 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.
Parametrics
PCD3311CT absolute maximum ratings: (1)VDD operating supply voltage: 2.5V to 6.0V; (2)IDD operating supply current: 0.9mA; (3)Istb standby current: 3mA; (4)VHG(RMS) DTMF HIGH group output voltage level (RMS value): 158V to 205mV; (5)VLG(RMS) DTMF LOW group output voltage level (RMS value): 125V to 160mV; (6)Gv pre-emphasis (voltage gain) of group: 1.85dB to 2.35dB; (7)THD total harmonic distortion: 25dB; (8)Tamb operating ambient temperature: -25℃ to +70℃.
Features
PCD3311CT features: (1)DTMF, modem and musical tone generation; (2)Stabilized output voltage level; (3)Low output distortion with on-chip filtering conforming to CEPT recommendations; (4)Latched inputs for data bus applications; (5)I2C-bus compatible; (6)Selection of parallel or serial (I2C-bus) data input (PCD3311C).
