TI公司的PCM3070嵌入了miniDSP的立体声音频CODEC,具又可编程的输入和输出,预定和参数化信号处理区块,集成PLL和LDO以及灵活的数字接口. 全编程的miniDSP支持录音和/或播放时的专用算法,立体声音频DAC的SNR为100dB, 立体声音频ADC的SNR为93dB,主要用在条形音箱,平板电视,MP3坞站,手机坞站以及其它立体声或2.1家用音频系统.本文介绍了PCM3070主要特性,方框图, 典型电路配置图以及PCM3070EVM-K评估模块与USB-MODEVM接口块主要特性,模块方框图,电路图和材料清单, 条形音箱参考设计主要特性,电路图, SoundBarProgrammer_RevA和RDK-Value-SB_RevA电路图与材料清单.
Stereo Audio Codec With Embedded miniDSP
The PCM3070 is a flexible stereo audio codec with programmable inputs and outputs,fully-programmable miniDSP, fixed predefined and parameterizable signal processing blocks, integrated PLL, integrated LDOs and flexible digital interfaces.
The PCM3070 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 speaker EQ, Crossovers, Dynamic Range Controls, Intelligent volume controls and other post-processing algorithms are loaded into the device after power-up.
