Powertune
The TLV320AIC3253 features PowerTune, a mechanism to balance power-versus-performance trade-offs at the
time of device configuration. The device can be tuned to minimize power dissipation, to maximize performance,
or to an operating point between the two extremes to best fit the application. The TLV320AIC3253 PowerTune
modes are called PTM_P1 to PTM_P4 for the playback (DAC) path.
For more detailed information see the Application Reference Guide, SLAU303
Digital Audio I/O Interface
Audio data is transferred between the host processor and the TLV320AIC3253 via the digital audio data serial
interface, or audio bus. The audio bus on this device is very flexible, including left or right-justified data options,
support for I2S or PCM protocols, programmable data length options, a TDM mode for multichannel operation,
very flexible master/slave configurability for each bus clock line, and the ability to communicate with multiple
devices within a system directly.
The audio bus of the TLV320AIC3253 can be configured for left or right-justified, I2S, DSP, or TDM modes of
operation, where communication with standard telephony PCM interfaces is supported within the TDM mode.
These modes are all MSB-first, with data width programmable as 16, 20, 24, or 32 bits by configuring Page 0,
Register 27, D(5:4). In addition, the word clock and bit clock can be independently configured in either Master or
Slave mode, for flexible connectivity to a wide variety of processors. The word clock is used to define the
beginning of a frame, and may be programmed as either a pulse or a square-wave signal. The frequency of this
clock corresponds to the maximum of the selected ADC and DAC sampling frequencies.
