The TLV320AIC3254-Q1 (also called the AIC3254- Q1) is a flexible, low-power, low-voltage stereo audio codec with programmable inputs and outputs, PowerTune capabilities, fully-programmable miniDSP, fixed predefined and parameterizable signal processing blocks, integrated PLL, integrated LDOs and flexible digital interfaces. The TLV320AIC3254-Q1 features two fully-programmable miniDSP cores that support application-specific algorithms in the record and-or the playback path of the device. The miniDSP cores are fully software controlled. Target algorithms, like active noise cancellation, acoustic echo cancellation or advanced DSP filtering are loaded into the device after power-up. Extensive register-based control of power, IO channel configuration, gains, effects, pin-multiplexing and clocks allows the device to be precisely targeted to its application. Combined with the advanced PowerTune technology, the device can cover operations from 8kHz mono voice playback to audio stereo 192kHz DAC playback, making it ideal for portable battery-powered audio and telephony applications. The record path of the TLV320AIC3254-Q1 covers operations from 8kHz mono to 192kHz stereo recording, and contains programmable input channel configurations covering single-ended and differential setups, as well as floating or mixing input signals. It also includes a digitally-controlled stereo microphone preamplifier and integrated microphone bias. Digital signal processing blocks can remove audible noise that may be introduced by mechanical coupling, such as optical zooming in a digital camera. The playback path offers signal-processing blocks for filtering and effects, and supports flexible mixing of DAC and analog input signals as well as programmable volume controls. The playback path contains two high-power output drivers as well as two fully-differential outputs. The high-power outputs can be configured in multiple ways, including stereo and mono BTL. The integrated PowerTune technology allows the device to be tuned to an optimum power-performance trade-off. Mobile applications frequently have multiple use cases requiring very low power operation while being used in a mobile environment. When used in a docked environment power consumption typically is less of a concern, while minimizing noise is important. With PowerTune, the TLV320AIC3254-Q1 addresses both cases.
