Inkcazelo yePCM1690
Isixhobo se-PCM1690 sisixhobo esiphezulu, i-chip-single, i-24-bit, i-channel eyisibhozo, i-audio digital-to-analog converter (DAC) eneziphumo ezihlukeneyo.Ishaneli esibhozo, i-24-bit ye-DAC isebenzisa imodyuli ephuculweyo, enemigangatho emininzi ye-delta-sigma (ΔΣ) kwaye ixhasa i-8-kHz ukuya kwi-192-kHz imilinganiselo yesampuli kunye ne-16-/20-/24-/32-bit ububanzi bedijithali. Igama elifakwe kwi-audio kujongano lomsindo.Ujongano oluvakalayo lwePCM1690 luxhasa ulwahlulo lwexesha-multiplexed (TDM) ifomathi ukongeza kumgangatho we-I.2S, ulungelelwaniso lwasekhohlo, olulungelelanisiweyo, kunye neefomathi ze-DSP.
I-PCM1690 inokulawulwa ngocingo oluthathu, ujongano oluhambelana ne-SPI, okanye ucingo olumbini,2I-C-compatible serial interface kwi-software, ebonelela ngokufikelela kuyo yonke imisebenzi equka ukuthomalalisa idijithali, i-soft bute, de-empasis, njalo njalo.Kwakhona, imowudi yokulawula i-hardware inikeza i-subset yemisebenzi enokucwangciswa komsebenzisi ngokusebenzisa izikhonkwane ezimbini zokulawula.I-PCM1690 ifumaneka kwi-12-mm × 8-mm (12-mm × 6-mm umzimba) iphakheji ye-HTSSOP-48.
Kuzo zonke iipakethe ezikhoyo, jonga i-adendum enolandelelwano ekupheleni kwephepha ledatha.
1. Ngoobani abasebenzi kwisebe lakho le-R & D?Ziziphi iziqinisekiso zakho?
-R & D UMlawuli: yenza isicwangciso sexesha elide seR & D senkampani kwaye ubambe isikhokelo sophando kunye nophuhliso;Ukukhokela kunye nokulawula isebe le-r&d ukuphumeza isicwangciso se-r&d yenkampani kunye nesicwangciso sonyaka se-R&D;Lawula inkqubela phambili yophuhliso lwemveliso kwaye uhlengahlengise isicwangciso;Misela uphando lwemveliso egqwesileyo kunye neqela lophuhliso, uphicotho kunye noqeqesho olunxulumene nabasebenzi bobugcisa.
Umphathi we-R & D: yenza imveliso entsha ye-R & D isicwangciso kwaye ubonise ukwenzeka kwesicwangciso;Ukongamela kwaye ulawule inkqubela kunye nomgangatho womsebenzi we-r&d;Phanda ngophuhliso lwemveliso entsha kwaye ucebise izisombululo ezisebenzayo ngokweemfuno zabathengi kwiinkalo ezahlukeneyo
Abasebenzi be-R&d: ukuqokelela kunye nokusombulula iinkcukacha eziphambili;inkqubo yeKhompyutha;Ukuqhuba iimvavanyo, iimvavanyo kunye nohlalutyo;Lungisa izixhobo kunye nezixhobo zovavanyo, iimvavanyo kunye nohlalutyo;Ukurekhoda idatha yokulinganisa, yenza izibalo kwaye ulungiselele iitshathi;Yenza uphando lwamanani
2. Yintoni uphando lwakho lwemveliso kunye nombono wophuhliso?
-Umbono wemveliso kunye nokukhethwa kwemveliso kunye novavanyo lwenkcazo yemveliso kunye noyilo lwesicwangciso seprojekthi kunye novavanyo lwemveliso kunye nokuqinisekiswa kokuqaliswa kwintengiso
