Txhais
Lub suab codec yog codec (ib lub cuab yeej lossis lub khoos phis tawj muaj peev xwm ntawm kev nkag los yog txiav txim siab cov ntaub ntawv digital) uas encodes lossis txiav suab.Hauv software, lub suab codec yog lub khoos phis tawj program uas siv lub algorithm uas compresses thiab decompresses cov ntaub ntawv audio raws li cov ntaub ntawv audio lossis streaming audio coding format.Lub algorithm aims los sawv cev rau high-fidelity suab teeb liab nrog ib tug tsawg kawg nkaus ntawm cov khoom thaum tuav zoo.
Txoj Cai Ua Haujlwm
Audio decoder chips ua haujlwm raws li cov hauv qab no.
1. Digitization ntawm lub teeb liab: digitization ntawm lub teeb liab txhais tau tias hloov lub teeb liab txuas ntxiv mus rau hauv cov teeb liab tsis sib xws, uas feem ntau yuav tsum muaj peb kauj ruam piv txwv, quantization, thiab coding.
2. Sampling: Qhov sib lawv liag ntawm cov teeb liab qauv qhov tseem ceeb ntawm qee lub sijhawm yog siv los hloov cov teeb liab txuas ntxiv rau lub sijhawm.
3. quantization: siv ib tug finite tus naj npawb ntawm amplitude approximation ntawm tus thawj nruam hloov nyob rau hauv lub sij hawm, lub analog teeb liab nruam amplitude mus rau ib tug finite tus naj npawb ntawm discrete qhov tseem ceeb nrog ib tug tej lub sij hawm luv luv.
4. encoding: raws li qee txoj cai, tus nqi sib txawv ntawm qhov sib txawv yog qhia hauv binary lej.Cov txheej txheem digitization saum toj no tseem hu ua Pulse Code Modulation (Pulse Code Modulation), feem ntau ua tiav los ntawm A / D converters.
5. audio sampling: sampling yog coj ntau tus qauv piv txwv qhov tseem ceeb los ntawm qhov sib txawv tsis tu ncua analog teeb liab nyob rau hauv lub sij hawm, los sawv cev rau qhov no tsis tu ncua sib txawv analog teeb liab.Ib qho kev sib txuas lus sib txuas ua ke hauv lub sij hawm thiab amplitude ntawm lub rooj ua haujlwm rau x (t), cov txheej txheem sampling yog ib txoj haujlwm ntawm x (t) nyob rau hauv lub sij hawm-discrete txheej txheem.General sampling yog ua nyob rau hauv lub sij hawm sib xws.Cia lub sij hawm no lub sij hawm yog T, ces tus qauv teeb liab yog x(nT), n yog ib tug zauv.
Khoom
TLV320AIC3101 yog lub suab qis qis lub suab codec nrog lub tso suab lub mloog pob ntseg amplifier, nrog rau ntau qhov kev tawm tswv yim thiab cov khoom siv uas yog programmable hauv ib qho kawg lossis tag nrho cov teeb tsa sib txawv.Kev tswj hwm lub zog raws li kev sau npe suav nrog, ua kom lub tso suab 48-kHz DAC playback tsawg li 14 mW los ntawm 3.3-V analog mov, ua rau nws zoo tagnrho rau cov khoom siv roj teeb uas siv lub suab thiab xov tooj.
Cov ntaub ntawv txoj kev ntawm TLV320AIC3101 muaj kev sib xyaw microphone kev tsis ncaj ncees, digitally tswj lub tso suab microphone preamplifier, thiab tsis siv neeg nce tswj (AGC), nrog kev sib xyaw / mux muaj peev xwm ntawm ntau yam analog inputs.Programmable filters muaj nyob rau hauv cov ntaub ntawv uas tuaj yeem tshem tawm cov suab nrov uas tuaj yeem tshwm sim thaum lub sijhawm kho qhov muag hauv cov koob yees duab digital.Txoj kev playback suav nrog kev sib xyaw / mux muaj peev xwm los ntawm lub tso suab DAC thiab xaiv cov khoom siv, los ntawm cov programmable ntim tswj, mus rau ntau yam khoom siv.
TLV320AIC3101 muaj plaub lub zog tso zis hluav taws xob nrog rau ob tus tsav tsheb sib txawv tag nrho.Cov tsav tsheb muaj zog muaj peev xwm tsav tau ntau yam kev teeb tsa, suav nrog txog li plaub txoj kab ntawm ib leeg-kawg 16-Ω lub mloog pob ntseg siv ac-coupling capacitors, lossis lub tso suab 16-Ω lub mloog pob ntseg hauv kev teeb tsa tsis muaj peev xwm.Tsis tas li ntawd, khub ntawm cov tsav tsheb tuaj yeem siv los tsav 8-Ω hais lus hauv BTL teeb tsa ntawm 500 mW ib channel.
Lub tso suab suab DAC txhawb nqa tus nqi piv txwv los ntawm 8 kHz txog 96 kHz thiab suav nrog cov programmable digital filtering hauv DAC txoj kev rau 3D, ntses bass thaj tsam, treble, midrange teebmeem, hais lus sib npaug, thiab de-emphasis rau 32-kHz, 44.1-kHz, thiab 48 -kHz piv txwv tus nqi.Lub tso suab suab ADC txhawb nqa tus nqi piv txwv los ntawm 8 kHz txog 96 kHz thiab ua ntej los ntawm programmable nce amplifiers lossis AGC uas tuaj yeem muab txog 59.5-dB analog nce rau qib qis microphone inputs.TLV320AIC3101 muab ntau yam kev ua haujlwm siab heev rau ob qho kev tawm tsam (8–1,408 ms) thiab kev lwj (0.05–22.4 vib nas this).Qhov AGC txuas ntxiv no tso cai rau AGC tuaj yeem hloov kho rau ntau hom kev siv.
Rau cov roj teeb txuag daim ntawv thov uas tsis xav tau analog lossis digital teeb liab ua tiav, cov cuab yeej tuaj yeem muab tso rau hauv qhov tshwj xeeb analog teeb liab passthrough hom.Hom no txo qis kev siv hluav taws xob ntau, vim tias feem ntau ntawm cov cuab yeej siv hluav taws xob poob thaum lub sijhawm ua haujlwm dhau los.
Lub tsheb npav serial tswj kev txhawb nqa I2C raws tu qauv, thaum lub tsheb npav serial audio data programmable rau I2S, sab laug / txoj cai-tsim, DSP, lossis TDM hom.Lub programmable PLL tau suav nrog rau lub sijhawm hloov pauv sijhawm thiab kev txhawb nqa rau txhua tus qauv suab tus nqi los ntawm ntau yam muaj MCLKs, sib txawv ntawm 512 kHz txog 50 MHz, nrog rau kev saib xyuas tshwj xeeb rau cov xwm txheej nrov tshaj plaws ntawm 12-MHz, 13- MHz, 16-MHz, 19.2-MHz, thiab 19.68-MHz system moos.
TLV320AIC3101 ua haujlwm los ntawm cov khoom siv analog ntawm 2.7 V-3.6 V, cov khoom siv digital ntawm 1.525 V-1.95 V, thiab cov khoom siv digital I / O ntawm 1.1 V-3.6 V. Cov cuab yeej muaj nyob rau hauv 5-mm × 5. -mm 32-pin QFN pob.
