Ibisobanuro

Kode ya majwi ni codec (igikoresho cyangwa porogaramu ya mudasobwa ishoboye gushishoza cyangwa gushushanya amakuru yamakuru ya digitale) ifunga cyangwa ikuraho amajwi.Muri porogaramu, codec y'amajwi ni porogaramu ya mudasobwa ishyira mu bikorwa algorithm ikanda kandi igahagarika amakuru y’amajwi ukurikije dosiye yatanzwe cyangwa uburyo bwo gufata amajwi.Algorithm igamije kwerekana ibimenyetso byamajwi byizerwa hamwe numubare muto wa bits mugihe ukomeza ubuziranenge.

Ihame ry'akazi

Chipode ya majwi ikora kumahame akurikira.

1. Gukwirakwiza ibimenyetso byamajwi: kubara ibimenyetso bisobanura guhindura ibimenyetso byikigereranyo bihoraho mubimenyetso byihariye bya digitale, mubisanzwe bisaba intambwe eshatu icyitegererezo, kubara, hamwe na code.

2. Icyitegererezo: Urukurikirane rwibimenyetso byerekana indangagaciro mugihe runaka bikoreshwa mugusimbuza ibimenyetso byumwimerere bikomeza mugihe.

3. kubara: ukoresheje umubare utagira ingano wa amplitude ugereranije nimpinduka yumwimerere ikomeza mugihe, ikimenyetso cyerekana analogi ikomeza amplitude mumubare utagira ingano yagaciro hamwe nigihe runaka.

4. kodegisi: ukurikije amategeko amwe, indangagaciro zingana zigaragazwa mumibare ibiri.Uburyo bwa digitifike yavuzwe haruguru buzwi kandi nka Pulse Code Modulation (Pulse Code Modulation), mubisanzwe bigerwaho nabahindura A / D.

5. gutoranya amajwi: icyitegererezo ni ugufata ibyitegererezo byinshi byerekana indangagaciro kuva muburyo butandukanye bwo kugereranya mugihe, kugirango ugaragaze iki kimenyetso gihoraho.Ikimenyetso gihoraho cyerekana amajwi mugihe hamwe na amplitude yimikorere yimbonerahamwe ya x (t), icyitegererezo ni imikorere ya x (t) mugihe-cyihariye.Icyitegererezo rusange gikorerwa mugihe kimwe.Reka iki gihe intera ibe T, hanyuma ibimenyetso byerekana ni x (nT), n kuba umubare usanzwe.

Ibicuruzwa

TLV320AIC3101 ni codec yimbaraga nkeya ya stereo yamajwi hamwe na stereo ya terefone yongerera imbaraga, kimwe ninjiza nyinshi nibisohoka bishobora gutegurwa muburyo bumwe cyangwa butandukanye rwose.Igenzura ryinshi rishingiye ku mashanyarazi ririmo, rituma stereo 48-kHz DAC ikinirwa munsi ya mW 14 kuva kuri 3.3-V igereranya, bigatuma biba byiza kuri bateri ikoreshwa na majwi na terefone.
Inzira yanditswemo ya TLV320AIC3101 ikubiyemo kubogama kwa mikoro ihuriweho, kugenzurwa na digitale ya stereo microphone preamplifier, hamwe no kugenzura inyungu byikora (AGC), hamwe no kuvanga / mux ubushobozi mubisubizo byinshi byinjira.Porogaramu ishobora gushungura iraboneka mugihe cyanditse gishobora gukuraho urusaku rwumvikana rushobora kubaho mugihe cyo guhitamo neza muri kamera ya digitale.Inzira yo gukinisha ikubiyemo kuvanga / mux ubushobozi buva kuri stereo DAC hamwe ninjiza zatoranijwe, binyuze muma progaramu ishobora kugenzurwa, kugeza kubisubizo bitandukanye.
TLV320AIC3101 ikubiyemo ibinyabiziga bine bisohora ingufu kimwe nabashoferi babiri batandukanye rwose.Imbaraga-zisohoka cyane zishobora gutwara ibinyabiziga bitandukanye, harimo imiyoboro igera kuri ine ya terefone imwe-imwe ya 16-Ω na terefone ukoresheje ac-guhuza imashini, cyangwa na stereo 16-Ω na terefone mu buryo butagaragara.Mubyongeyeho, ibice bibiri byabashoferi birashobora gukoreshwa mugutwara 8-Ω abavuga muburyo bwa BTL kuri 500 mW kumuyoboro.
Stereo amajwi DAC ishyigikira igipimo cyicyitegererezo kuva kuri 8 kHz kugeza kuri 96 kHz kandi ikubiyemo gushungura porogaramu zishobora gukoreshwa mu nzira ya DAC ya 3D, bass, treble, ingaruka za midrange, kuringaniza imvugo, no gushimangira 32-kHz, 44.1-kHz, na 48 -kHz ibipimo by'icyitegererezo.Stereo amajwi ADC ishyigikira igipimo cyikitegererezo kuva 8 kHz kugeza kuri 96 kHz kandi kibanzirizwa ninyungu zishobora kwongerwaho porogaramu cyangwa AGC zishobora gutanga inyungu zigera kuri 59.5-dB zunguka kuri mikoro yo hasi.TLV320AIC3101 itanga intera ndende cyane ya programme yibitero byombi (8-1408 ms) no kubora (amasegonda 0.05-222.4).Iyi ntera yagutse ya AGC yemerera AGC guhuzwa kubwoko bwinshi bwa porogaramu.
Kubikoresho byo kubika bateri aho bitagereranywa cyangwa gutunganya ibimenyetso bya digitale bisabwa, igikoresho gishobora gushyirwaho muburyo bwihariye bwo kugereranya ibimenyetso.Ubu buryo bugabanya cyane gukoresha ingufu, kuko ibyinshi mubikoresho bikoreshwa munsi yiki gikorwa.
Bisi igenzura bisi ishyigikira protocole ya I2C, mugihe bisi yamakuru yamakuru ya bisi ishobora gutegurwa kuri I2S, ibumoso / iburyo-bifite ishingiro, DSP, cyangwa TDM.Porogaramu ishobora gukoreshwa cyane ya PLL yashyizwemo kubyara amasaha yoroheje no gushyigikirwa kubiciro byose byamajwi kuva MCLKs iboneka, bitandukanye kuva 512 kHz kugeza kuri 50 MHz, hitawe cyane cyane kubibazo bizwi cyane bya 12-MHz, 13- MHz, 16-MHz, 19.2-MHz, na 19.68-MHz amasaha ya sisitemu.
TLV320AIC3101 ikorera muburyo butandukanye bwa 2.7 V - 3.6 V, itangwa rya digitale ya 1.525 V - 1.95 V, hamwe na Digital I / O itanga 1.1 V - 3.6 V. Igikoresho kiraboneka muri 5-mm × 5 -mm 32-pin ya QFN.
