Ibisobanuro

ADAU1452 / ADAU1451 / ADAU1450 ni abatwara amajwi yujuje ibyangombwa bitwara amajwi arenze kure ubushobozi bwo gutunganya ibimenyetso bya digitale y'ibikoresho bya SigmaDSP® byabanje.Ibyuma byubatswe byubatswe byateguwe neza kugirango bitunganyirizwe neza.Gutunganya amajwi algorithms bigaragarira mubyitegererezo-byintangarugero na blok-by-blok paradigms zishobora gukorerwa icyarimwe mugihe cyo gutangiza ibimenyetso byakozwe hakoreshejwe igikoresho gishushanya porogaramu, SigmaStudio ™.Ivugurura ryibikoresho bya digitale (DSP) byubatswe byubaka bituma ubwoko bumwebumwe bwo gutunganya amajwi algorithms bikorwa hakoreshejwe amabwiriza make cyane ugereranije nibisabwa kumasekuruza yabanjirije SigmaDSP, biganisha kumikorere ya code neza.1.2 V, 32-bit ya DSP yibanze irashobora gukora kuri frequence igera kuri 294.912 MHz kandi igasohoza amabwiriza agera kuri 6144 kuri sample kurugero rusanzwe rwa 48 kHz.Ariko, usibye ibiciro-byinganda-nganda, intera nini yikigereranyo irahari.Imibare ya PLL hamwe nibikoresho byoroshye bitanga amasaha arashobora kubyara icyarimwe amajwi agera kuri 15 icyarimwe.Amashanyarazi yisaha, hamwe nu ndege ya asinchronous sample igipimo cyo guhindura (ASRCs) hamwe na matrike yoroheje yerekana ibyuma byerekana amajwi, bituma ADAU1452 / ADAU1451 / ADAU1450 ihuriro ryamajwi ryorohereza cyane igishushanyo mbonera cya sisitemu y'amajwi menshi.Imigaragarire ya ADAU1452 / ADAU1451 / ADAU1450 hamwe n’urwego runini rw’ibihinduka-bigereranywa na sisitemu (ADCs), ibyuma bifata amajwi-bigereranya (DACs), ibyuma bifata amajwi bya digitale, ibyuma byongera imbaraga, hamwe n’umuzunguruko, kubera ibyambu byabo bikurikirana cyane, Imigaragarire ya S / PDIF (kuri ADAU1452 na ADAU1451), hamwe ninshuro nyinshi zinjiza / ibisohoka.Ibikoresho birashobora kandi guhuza byimazeyo na pulse yubucucike (PDM) isohoka mikoro mikoro (MEMS) mikoro, bitewe na decimation ihuriweho hamwe yabigenewe yabigenewe.Umucakara wigenga na shobuja I2 C / serial periferique (SPI) ibyambu bigenzura byemerera ADAU1452 / ADAU1451 / ADAU1450 ntabwo byateganijwe gusa kandi bigashyirwaho nigikoresho cyibanze cyo hanze, ariko kandi gukora nka mastersthat irashobora guteganya no kugena ibikoresho byabacakara bitaziguye.Ihinduka, rifatanije no kwikorera boot boot imikorere, ituma igishushanyo cya sisitemu yihariye idasaba kwinjiza hanze gukora.
