Sharaxaada
ADAU1452/ADAU1451/ADAU1450 waa soosaarayaal maqal ah oo uqalma baabuurta kuwaas oo aad uga badan awoodaha farsamaynta calaamadaha dhijitaalka ah ee aaladaha SigmaDSP® hore.Qaab dhismeedka qalabka dib loo habeeyay ayaa loo hagaajiyay habaynta maqalka oo hufan.Algorithms-ka habaynta maqalka waxaa lagu xaqiiqsaday muunad-muunad-iyo-block-by-block paradigms kuwaas oo labadaba lagu fulin karo isku mar iyadoo la adeegsanayo socodka hab-socodka signalka ee la abuuray iyadoo la adeegsanayo aaladda barnaamijyada garaafyada, SigmaStudio ™.Farsamaynta calaamadaha dhijitaalka ah ee dib loo habeeyay (DSP) ayaa u sahlaysa qaar ka mid ah noocyada habaynta maqalka ee algorithms in la fuliyo iyadoo la adeegsanayo tilmaamo aad uga yar sidii looga baahnaa jiilalkii hore ee SigmaDSP, taasoo horseedaysa hufnaanta koodhka si wayn loo hagaajiyay.Xudunta 1.2 V, 32-bit DSP waxay ku socon kartaa ilaa 294.912 MHz waxayna fulin kartaa ilaa 6144 tilmaamo muunadkiiba heerka muunada caadiga ah ee 48 kHz.Si kastaba ha ahaatee, marka lagu daro heerarka heerka warshadaha, heerar muunado oo kala duwan ayaa la heli karaa.Integer PLL iyo qalabka saacada dabciga ah ayaa dhalin kara ilaa 15 muunad muunad maqal ah isku mar.Soosaarayaashan saacada, oo ay weheliyaan dusha sare ee beddelayaasha muunada muunada asynchronous (ASRCs) iyo jaantuska habaynta maqalka ee qalabaysan oo dabacsan, waxay ka dhigayaan ADAU1452/ADAU1451/ADAU1450 xudunta maqalka ugu fiican oo si weyn u fududaysa naqshadaynta nidaamyada maqalka ee isku dhafan.Isku xirka ADAU1452/ADAU1451/ADAU1450 oo leh noocyo badan oo isbedbeddelaya analog-to-dijital (ADCs), beddelayaasha-dijitaalka-ilaa-analoogga (DACs), aaladaha maqalka dhijitaalka ah, cod-weyneyaasha, iyo wareegga koontaroolka, sababtoo ah dekedo taxane ah oo aadka loo habeyn karo, Isku-xidhka S/PDIF (ku ADAU1452 iyo ADAU1451), iyo biinanka wax-soo-gelinta ee ujeedooyinka badan leh.Qalabku waxa kale oo ay si toos ah ula xidhiidhi karaan modajinta cufnaanta garaaca wadnaha (PDM) makarafoonnada microelectromechanical (MEMS), sababtoo ah filtarrada jajabinta isku dhafan ee si gaar ah loogu talagalay ujeedadaas.Addoon madax-bannaan iyo sayid I2 C / serial peripheral interface (SPI) dekedaha gacanta ku ADAU1452 / ADAU1451 / ADAU1450 ma aha oo kaliya in la barnaamijiyo oo lagu habeeyey by qalab Master dibadda ah, laakiin sidoo kale in ay u dhaqmaan sidii mastersthat si toos ah barnaamijka iyo habayn kara qalabka addoonta dibadda.Dabacsanaantan, oo ay weheliso shaqeynta is-bootka, waxay awood u siineysaa naqshadeynta nidaamyada gooni-goonida ah ee aan u baahnayn wax gelinta dibadda ah si ay u shaqeyso.
