Incazelo

I-ADAU1452/ADAU1451/ADAU1450 amaphrosesa womsindo wezimoto adlula kude amandla okucubungula isignali yedijithali amadivayisi angaphambilini e-SigmaDSP®.Isakhiwo sezingxenyekazi zekhompuyutha esimiswe kabusha sithuthukiselwe ukucutshungulwa komsindo okusebenzayo.Ama-algorithms okucubungula umsindo enziwa ngesampula-by-sample kanye nama-block-by-block paradigm angenziwa womabili ngesikhathi esisodwa ekugelezeni kokucubungula isignali okudalwe kusetshenziswa ithuluzi lokuhlela lesithombe, i-SigmaStudio™.I-architecture eyinhloko ye-Digital signal processor (DSP) eyenza ezinye izinhlobo zama-algorithms okucubungula umsindo zisetshenziswe kusetshenziswa imiyalelo embalwa kakhulu kunaleyo ebidingeka ezizukulwaneni zangaphambili ze-SigmaDSP, okuholela ekusebenzeni kahle kwekhodi okuthuthuke kakhulu.I-1.2 V, 32-bit DSP core ingasebenza kumafrikhwensi afika ku-294.912 MHz futhi isebenzise imiyalelo efika ku-6144 isampula ngayinye ngesilinganiso sesampula esijwayelekile esingu-48 kHz.Kodwa-ke, ngaphezu kwamazinga ajwayelekile embonini, kunezinhlobo eziningi zezilinganiso zesampula ezitholakalayo.I-PLL ephelele kanye nehardware ye-clock generator eguquguqukayo ingakwazi ukukhiqiza amasampula omsindo afinyelela kuzilinganiso eziyi-15 ngesikhathi esisodwa.Lawa majeneretha wewashi, kanye neziguquli zesampula ezingavumelaniyo (ama-ASRC) kanye ne-matrix yomzila womsindo wehadiwe eguqukayo, zenza i-ADAU1452/ADAU1451/ADAU1450 amahabhu omsindo afaneleka kakhulu enza lula ukwakheka kwezinhlelo zomsindo eziningi eziyinkimbinkimbi.Isixhumi esibonakalayo se-ADAU1452/ADAU1451/ADAU1450 esinohlu olubanzi lweziguquli ze-analog-to-digital (ADCs), iziguquli zedijithali-kuya-analog (ama-DAC), amadivaysi omsindo wedijithali, izikhulisi, kanye nokujikeleza kokulawula, ngenxa yamachweba azo ahlelekeka kakhulu, Izixhumi ezibonakalayo ze-S/PDIF (ku-ADAU1452 ne-ADAU1451), namaphinikhodi okokufaka/okukhiphayo anezinhloso eziningi.Amadivayisi angaphinde axhumane ngokuqondile namamakrofoni we-pulse density modulation (PDM) okukhiphayo we-microelectromechanical (MEMS), ngenxa yezihlungi ezihlanganisiwe zokuqeda amandla eziklanyelwe leyo njongo.Izimbobo zokulawula zesigqila ezizimele kanye ne-master I2 C/serial peripheral interface (SPI) zivumela i-ADAU1452/ADAU1451/ADAU1450 ukuthi ingagcini nje ngokuhlelwa futhi imiswe idivayisi eyinhloko yangaphandle, kodwa futhi yenze njengongcweti abangahlela futhi balungiselele amadivayisi angaphandle wesigqila ngokuqondile.Lokhu kuvumelana nezimo, kuhlanganiswe nokusebenza kwe-self boot, kunika amandla ukuklanywa kwamasistimu azimele angadingi noma yikuphi okokufaka kwangaphandle ukuze kusebenze.
