Ingcaciso

I-codec ye-audio yi-codec (isixhobo okanye inkqubo yekhompyutha ekwazi ukufaka iikhowudi okanye ukukhupha ikhowudi yedatha yedijithali) edibanisa okanye ikhuphe i-audio.Kwi-software, i-codec yomsindo yinkqubo yekhompyutha esebenzisa i-algorithm ecinezelayo kwaye ithobe idatha ye-audio yedijithali ngokuhambelana nefayile ye-audio enikeziweyo okanye ifomathi ye-audio coding format.I-algorithm ijolise ekuboniseni i-high-fidelity audio signal kunye nenani elincinci leebhithi ngelixa ligcina umgangatho.

Umgaqo wokuSebenza

Iitshiphusi zedikhowuda zomsindo zisebenza kule migaqo ilandelayo.

1. Ukwenziwa kweDijithali yesiginali ye-audio: ukufakwa kwedijithali kwisiginali kuthetha ukuguqula isiginali ye-analog eqhubekayo ibe ngumqondiso ocacileyo wedijithali, odinga ngokubanzi amanyathelo amathathu isampuli, ubungakanani kunye nekhowudi.

2. Isampulu: Ulandelelwano lwamaxabiso eisampulu zomqondiso kumaxesha athile lusetyenziselwa ukubuyisela umqondiso oqhubekayo ngexesha.

3. quantization: usebenzisa inani eliqingqiweyo lokulinganisa kwe-amplitude yenguqu yokuqala eqhubekayo ngexesha, isignali ye-analog eqhubekayo ye-amplitude ibe yinani eliqingqiweyo lamaxabiso ahlukeneyo kunye nexesha elithile.

4. i-encoding: ngokwemigaqo ethile, amaxabiso adityanisiweyo abonakaliswe ngamanani okubini.Inkqubo yedijithali engentla yaziwa ngokuba yi-Pulse Code Modulation (I-Pulse Code Modulation), edla ngokufezekiswa ngabaguquli be-A / D.

5. isampulu yomsindo: isampulu kukuthatha amaxabiso esampulu abameli abaninzi ukusuka kwisignali eyohlukileyo ye-analog ngexesha, ukumela lo mqondiso we-analog oqhubekayo.Isiginali ye-audio ye-analog eqhubekayo ngexesha kunye nobukhulu betafile yomsebenzi we-x (t), inkqubo yesampuli ngumsebenzi we-x (t) kwinkqubo ecacileyo yexesha.Iisampulu jikelele iqhutywa ngamaxesha afanayo.Vumela elixesha lokuphumla libe ngu T, emva koko umqondiso wesampuli ngu x(nT), n ibe linani eli-natural.

Imveliso

I-TLV320AIC3101 yi-codec yomsindo westereo enamandla aphantsi ene-stereo headphone amplifier, kunye namagalelo amaninzi kunye neziphumo ezicwangciswayo kuqwalaselo oluphela okanye olwahlukileyo ngokupheleleyo.Ulawulo lwamandla olusekelwe kwirejista olubanzi lubandakanyiwe, lwenza ukuba i-stereo 48-kHz DAC idlale isezantsi njenge-14 mW ukusuka kubonelelo lwe-analog ye-3.3-V, iyenza ilungele ukusetyenziswa kwe-audio enebhetri ephathwayo kunye neefowuni.
Indlela yokurekhoda ye-TLV320AIC3101 iqulethe i-microphone bias edibeneyo, i-microphone elawulwa ngedijithali ye-microphone preamplifier, kunye nolawulo lokuzuza ngokuzenzekelayo (AGC), kunye nekhono lokuxuba / i-mux phakathi kweegalelo ezininzi ze-analog.Izihluzi ezicwangcisiweyo ziyafumaneka ngexesha lerekhodi elinokuthi lisuse ingxolo evakalayo enokuthi yenzeke ngexesha lokusondeza kwikhamera yedijithali.Umzila wokudlala uquka ukuxuba / amandla e-mux ukusuka kwi-stereo DAC kunye negalelo elikhethiweyo, ngokusebenzisa ulawulo lwevolumu olucwangcisiweyo, ukuya kwiziphumo ezahlukeneyo.
I-TLV320AIC3101 iqulethe abaqhubi abane bemveliso ephezulu kunye nabaqhubi ababini abaphuma ngokupheleleyo.Abaqhubi abakhupha amandla aphezulu bayakwazi ukuqhuba ukucwangciswa komthwalo ohlukeneyo, kubandakanywa ukuya kuthi ga kwiitshaneli ezine ze-16-Ω ezigqityiweyo ze-headphones usebenzisa i-ac-coupling capacitors, okanye i-stereo 16-Ω i-headphones kwi-capless output configuration.Ukongeza, izibini zabaqhubi zingasetyenziselwa ukuqhuba izithethi ze-8-Ω kuqwalaselo lwe-BTL kwi-500 mW ngetshaneli nganye.
I-DAC yomsindo westereo ixhasa amaxabiso esampuli ukusuka kwi-8 kHz ukuya kwi-96 kHz kwaye ibandakanya ukuhluzwa kwedijithali okucwangcisiweyo kwindlela ye-DAC ye-3D, i-bass, i-treble, iziphumo ze-midrange, ukulinganisa kwesithethi, kunye nogxininiso lwe-32-kHz, 44.1-kHz, kunye ne-48 -kHz iireyithi zeesampulu.I-ADC yomsindo we-stereo ixhasa iireyithi zesampulu ukusuka kwi-8 kHz ukuya kwi-96 kHz kwaye ilandelwa yi-programmable gain amplifiers okanye i-AGC enokubonelela ukuya kuthi ga kwi-59.5-dB inzuzo ye-analog ye-low-level microphone inputs.I-TLV320AIC3101 ibonelela ngoluhlu oluphezulu kakhulu lwenkqubo yokuhlaselwa kokubini (8-1,408 ms) kunye nokubola (0.05-22.4 imizuzwana).Olu luhlu lwandisiweyo lwe-AGC luvumela i-AGC ukuba ilungelelanise iindidi ezininzi zezicelo.
Kwiinkqubo zogcino lwebhetri apho kungafunekiyo ukusetyenzwa kwe-analog okanye isignali yedijithali, ifowuni inokubekwa ngendlela ekhethekileyo yophawu lokugqitha.Le ndlela inciphisa kakhulu ukusetyenziswa kwamandla, njengoko uninzi lwesixhobo lusebenza phantsi ngexesha lo msebenzi wokudlula.
Ibhasi yokulawula i-serial ixhasa i-protocol ye-I2C, ngelixa ibhasi yedatha ye-serial audio icwangciselwe i-I2S, i-left / right-justified, DSP, okanye iindlela ze-TDM.I-PLL ecwangciswe kakhulu ibandakanyiwe ekuveliseni iwotshi eguquguqukayo kunye nenkxaso yazo zonke iireyithi zomsindo eziqhelekileyo ukusuka kuluhlu olubanzi lwee-MCLK ezikhoyo, ezahlukeneyo ukusuka kwi-512 kHz ukuya kwi-50 MHz, ingqalelo ekhethekileyo ehlawulwe kwezona meko zidumileyo ze-12-MHz, i-13- MHz, 16-MHz, 19.2-MHz, kunye ne-19.68-MHz iiwotshi zenkqubo.
I-TLV320AIC3101 isebenza kwi-analog supply ye-2.7 V-3.6 V, i-digital core supply ye-1.525 V-1.95 V, kunye ne-digital I / O ye-1.1 V-3.6 V. Isixhobo sifumaneka kwi-5-mm × 5 -mm 32-pin QFN iphakheji.
