Powertune
The TLV320AIC3204 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.
For more detailed information see the TLV320AIC3204Application Reference Guide, SLAA557.
Digital Audio IO Interface
Audio data flows between the host processor and the TLV320AIC3204 on the digital audio data serial interface,
or audio bus. This very flexible bus includes left or right-justified data options, support for I
2
S 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 TLV320AIC3204 can be configured for left or right-justified, I
2
S, 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.
