Overview
TLV320AIC1109 PCM CODEC SLAS358 – DECEMBER 2001 FEATURES D 2.
7-V Operation D Two Differential Microphone Inputs, One Differential Earphone Output, and One Single-Ended Earphone Output D Programmable Gain Amplifiers for Transmit, Receive, Sidetone, and Volume Control D Earphone Mute and Microphone Mute D On-Chip I2C-Bus, Which Provides a Simple, Standard, Two-Wire Serial Interface With Digital ICs D Programmable for 15-Bit Linear Data or 8-Bit Companded (µ-Law or A-Law) Mode D 32-Terminal TQFP Package D Designed for Analog and Digital Wireless Handsets and Telecommunications Applications D Dual-Tone Multifrequency (DTMF) D Pulse Density Modulated (PDM) Buzzer Output APPLICATIONS D Digital Handset D Digital Headset D Cordless Phones D Digital PABX D Digital Voice Recording DESCRIPTION The PCM codec is designed to perform the transmit encoding analog/digital (A/D) conversion and receive decoding digital/analog (D/A) conversion, together with transmit and receive filtering, for voice-band communications systems.
The device operates in either the 15-bit linear or 8-bit companded (µ-law or A-Law) mode, which is selectable through the I2C interface.
From a 2.
048-MHz master clock input, the PCM codec generates its own internal clocks.
