Product Overview

The TLV320AIC20KIPFB is a low-power stereo Voice-band Codec with 8R speaker amplifiers. It features two 16-bit analog-to-digital (A/D) channels and two 16-bit digital-to-analog (D/A) channels, which can be connected to a handset, headset, speaker, microphone, or a subscriber line via a programmable analog cross point. The TLV320AIC2x provides high resolution signal conversion from digital-to-analog (D/A) and from analog-to-digital (A/D) using oversampling sigma-delta technology with programmable sampling rate. It implements the smart time division multiplexed serial port (SMARTDM™). The SMARTDM port is a synchronous 4-wire serial port in TDM format for glue-free interface to TI DSPs and microcontrollers. The SMARTDM™ supports both continuous data transfer mode and on-the-fly reconfiguration programming mode. The TLV320AIC2x can be gluelessly cascaded to any SMARTDM-based device to form a multichannel codec and up to eight TLV320AIC2x codecs can be cascaded to a single serial port.
  • Stereo 16-bit oversampling sigma-delta D/A converter
  • Selectable FIR/IIR filter with bypassing option
  • Maximum 26Ksps with on-chip IIR/FIR filter
  • Maximum 104Ksps with IIR/FIR bypassed
  • Glueless 4-wire interface to DSP
  • Programming mode to allow on-the-fly reconfiguration
  • Continuous data transfer mode to minimize bit clock speed
  • Support different sampling rate for each device
  • Allows up to eight devices to be connected to a single serial port
  • Differential and single-ended analog input/output
  • Green product and no Sb/Br
