TLV320AIC13

The TLV320AIC13 implements the smart time division multiplexed serial port (SMARTDM™). This design innovation optimizes the DSP performance with an advanced synchronous serial port in TDM format for glue-free interface to popular DSPs (i.e., C5x, C6x) and microcontrollers. The SMARTDM supports both continuous data transfer mode and on-the-fly reconfiguration programming mode. The advantage of SMARTDM is to maximize the bandwidth of data transfer between the TLV320AIC13 DSP codec and the DSP. In normal operation, it automatically detects the number of codecs in the serial interface and adjusts the number of time slots to match the number of codecs so that no time slot in the TDM frame is wasted. In the turbo mode, it maintains the same number of time slots but maximizes the bit transferred rate to 25 MHz to give the DSP more bandwidth to process other tasks in the same sampling period. The SMARTDM technology allows up to 16 codec to share a single 4-wire serial bus.

The TLV320AIC13 also provides a flexible host port. The host port interface is a two-wire serial interface that can be programmed to be either an industrial standard I²C or a simple S²C (start-stop communication protocol).

The TLV320AIC13 also integrates all of the critical functions needed for most voice-band applications including MIC preamp, handset/headset preamps, antialiasing filter (AAF), input/output programmable gain amplifier (PGA), and selectable low-pass IIR/FIR filters.

The TLV320AIC13 implements an extensive power management; including device power-down, independent software control for turning off ADC, DAC, op-amps, and IIR/FIR filter (bypassable) to maximize system power conservation. The TLV320AIC13 consumes only 10 mW at 3 V without 16- drivers.

The TLV320AIC13’s low power operation from 2.7-V to 3.6-V for analog and I/O and 1.65 V to 1.95 for digital core power supplies, along with extensive power management, 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 or multichannel active control applications.

The wide range of low-voltage I/O (1.1 V–3.6 V) enables the AIC13 to interface with a single power supply, or with dual power supplies for mixed low-voltage DSP systems such as the TMS320UC54x. This feature eliminates the need for external level-shifting and reduces power consumption

The TLV320AIC13 is characterized for commercial operation from 0°C to 70°C and industrial operation from –40°C to 85°C.
