Description for the TLV320AIC15

The TLV320AIC15 implements the smart time division multiplexed serial port (SMARTDM™). This is TI’s design innovation to optimize DSP performance with its most 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. SMARTDM maximizes the bandwidth of data transfer between the TLV320AIC15 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 codecs to share a single 4-wire serial bus.

The TLV320AIC15 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 TLV320AIC15 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 TLV320AIC15 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 TLV320AIC15 consumes only 10 mW at 3 V.

The TLV320AIC15’s low power operation from 2.7-V to 3.6-V for analog and I/O and 1.65 V to 1.95 V 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 AIC15 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 TLV320AIC15 is characterized for commercial operation from 0°C to 70°C and industrial operation from –40°C to 85°C.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
