Product Summary
The TLV320AIC20IPFB is a low－cost, low－power, highly－integrated, high－performance, dual－voice codec. The TLV320AIC20IPFB 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 crosspoint. The TLV320AIC20IPFB 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. The TLV320AIC20IPFB implements the smart time division multiplexed serial port (SMARTDMTM). The SMARTDM port is a synchronous 4－wire serial port in TDM format for glue－free interface to TI DSPs (i.e., TMS320C5000 TMS320C6000 DSP platforms) and microcontrollers. The SMARTDMTM supports both continuous data transfer mode and on－the－fly reconfiguration programming mode. The TLV320AIC20IPFB 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.
