I-ADAU1452WBCPZ-RL IC AUDIO PROCESSOR 72LFCSP

Inkcazo

I-ADAU1452/ADAU1451/ADAU1450 ziinkqubo zeaudio ezifanelekileyo ezigqithise kakhulu ubunakho bokwenza umqondiso wedijithali kwizixhobo zangaphambili zeSigmaDSP®.Ulwakhiwo lwe-hardware oluhlaziyiweyo lwenzelwe ukusetyenzwa kakuhle komsindo.Ii-algorithms zokucutshungulwa komsindo ziyenzeka kwisampulu-nge-sampulu kunye ne-block-by-block paradigms ezinokuthi zenzeke zombini ngaxeshanye kwindlela yokuhambisa umqondiso owenziwe kusetyenziswa isixhobo senkqubo yegraphical, iSigmaStudio™.Iprosesa ehlaziyiweyo yedijithali yedijithali (i-DSP) uyilo olusisiseko lwe-architecture luvumela ukuba ezinye iintlobo ze-algorithms zokucutshungulwa komsindo ziphunyezwe kusetyenziswa imiyalelo embalwa kakhulu kunokuba ibifuneka kwizizukulwana zangaphambili ze-SigmaDSP, ezikhokelela kuphuculo olukhulu lwekhowudi.I-1.2 V, i-32-bit ye-DSP engundoqo inokusebenza kwiifrikhwensi ukuya kwi-294.912 MHz kwaye iqhube ukuya kwi-6144 imiyalelo ngesampuli kwireyithi eqhelekileyo ye-48 kHz.Nangona kunjalo, ukongeza kumaxabiso akumgangatho weshishini, uluhlu olubanzi lweereyithi zesampulu ziyafumaneka.I-PLL epheleleyo kunye ne-hardware ye-clock generator eguquguqukayo inokuvelisa ukuya kuthi ga kwi-15 imilinganiselo yesampulu yomsindo ngaxeshanye.Ezi generator zewotshi, kunye ne-asynchronous converter rate rate rate (ASRCs) kunye ne-hardware eguquguqukayo ye-audio ye-matrix yomzila, yenza i-ADAU1452/ADAU1451/ADAU1450 ii-audio hubs ezifanelekileyo ezenza lula kakhulu uyilo lweenkqubo zomsindo ezininzi.Ujongano lwe-ADAU1452/ADAU1451/ADAU1450 olunoluhlu olubanzi lwabaguquli be-analog-to-digital (ADCs), abaguquli bedijithali ukuya kwi-analog (DACs), izixhobo zomsindo wedijithali, i-amplifiers, kunye nolawulo lwesekethe, ngenxa yezibuko zabo eziqwalaselwe kakhulu, Ujongano lwe-S/PDIF (kwi-ADAU1452 kunye ne-ADAU1451), kunye ne-multipurpose input/output pins.Izixhobo zinokuthi zijongane ngokuthe ngqo kunye ne-pulse density modulation (PDM) i-microelectromechanical (MEMS) i-microphone ephumayo, ngenxa yeefilitha ezidibeneyo zokunciphisa i-decimation eyenzelwe ngokukodwa loo njongo.Ikhoboka elizimeleyo kunye nenkosi ye-I2 C / i-serial peripheral interface (SPI) yokulawula izibuko ivumela i-ADAU1452/ADAU1451/ADAU1450 ukuba ingacwangciswanga kwaye iqwalaselwe sisixhobo esilawulayo sangaphandle, kodwa iphinde isebenze njenge-mastersthat inokulungiselela kwaye iqwalasele izixhobo zekhoboka zangaphandle ngokuthe ngqo.Oku bhetyebhetye, kudityaniswe nokusebenza kwe-self boot, kwenza uyilo lweenkqubo ezizimeleyo ezingadingi naliphi na igalelo langaphandle ukuze lisebenze.
