Description

The TLV320AIC1x is a true low-cost, low-power, high-integrated, high-performance, mono voice codec. Itfeatures one 16-bit analog-to-digital (A/D) channel and one 16-bit digital-to-analog (D/A) channel.The TLV320AIC24CPFBR provides high-resolution signal conversion from digital-to-analog (D/A) and fromanalog-to-digital (A/D) using oversampling sigma-delta technology with programmable sampling rate.The TLV320AIC1x implements the smart time division multiplexed serial port (SMARTDM™). The SMARTDMport is a synchronous 4-wire serial port in TDM format for glue-free interface to TI DSPs (i.e. TMS320C5000™,TMS320C6000™) and microcontrollers. The SMARTDM supports both continuous data transfer mode andon-the-fly reconfiguration programming mode. The TLV320AIC1x can be gluelessly cascaded to anySMARTDM-based device to form multichannel codec and up to 16 TLV320AIC1x codecs can be cascaded to asingle serial port.The TLV320AIC1x also provides a flexible host port. The host port interface is a two-wire serial interface thatcan be programmed to be either an industrial standard I2C or a simple S2C (start-stop communication protocol).The TLV320AIC1x also integrates all of the critical functions needed for most voice-band applcations includingMIC preamplifier, handset amplifier, headset amplifier, antialiasing filter (AAF), input/output programmable gainamplifier (PGA), and selectable low-pass IIR/FIR filters. The AIC12K also includes an 8-W speaker driver.The TLV320AIC1x implements an extensive power management; including device power-down, independentsoftware control for turning off ADC, DAC, operational-amplifiers, and IIR/FIR filter (bypass) to maximize systempower conservation. The TLV320AIC1x consumes only 11.2 mW at 3.3 V.The TLV320AIC1x low power operation from 2.7 V to 3.6 V power supplies, along with extensive powermanagement, make it ideal for portable applications including wireless accessories, hands free car kits, VOIP,cable modem, and speech processing. Its low group delay characteristic makes it suitable for single ormultichannel active control applications.The TLV320AIC1x is characterized for commercial operation from 0°C to 70°C and industrial operation from-40°C to 85°C. The TLV320AIC1xk is characterized for industrial operation from -40°C to 85°C.
