Ibisobanuro kuri PCM1690
Igikoresho cya PCM1690 nigikorwa cyinshi, chip-imwe, 24-bit, umuyoboro umunani, amajwi ya digitale-igereranya (DAC) hamwe nibisubizo bitandukanye.Imiyoboro umunani, 24-bit DAC ikoresha moderi yongerewe imbaraga, urwego rwinshi rwa delta-sigma (ΔΣ) kandi ishyigikira 8-kHz kugeza 192-kHz yikigereranyo hamwe na 16- / 20- / 24- / 32-bit ya digitale ijambo ryinjiza ijambo kumurongo wamajwi.Imigaragarire y amajwi ya PCM1690 ishyigikira imiterere-igabana-igizwe na (TDM) yongeyeho ibisanzwe I2S, ibumoso-bufite ishingiro, iburyo-bufite ishingiro, na DSP.
PCM1690 irashobora kugenzurwa hifashishijwe insinga eshatu, interineti ihuza SPI, cyangwa insinga ebyiri, I.2Imigaragarire ya C ihujwe muri software, itanga uburyo bwo gukora imirimo yose harimo na attenuation ya digitale, ibiragi byoroshye, de-gutsindagira, nibindi nibindi.Na none, uburyo bwo kugenzura ibyuma bitanga igice cyumukoresha-porogaramu ikora binyuze mumashini abiri yo kugenzura.PCM1690 iraboneka muri 12-mm × 8-mm (12-mm × 6-mm umubiri) HTSSOP-48.
Kubintu byose biboneka, reba ibyongeweho byongeweho kumpapuro zamakuru.
1. Ni bande bakozi mu ishami rya R & D?Ni ubuhe bushobozi bwawe?
-R & D Umuyobozi: gutegura gahunda yigihe kirekire yikigo no gusobanukirwa icyerekezo cyubushakashatsi niterambere;Kuyobora no kugenzura ishami rishyira mubikorwa ingamba za sosiyete na gahunda ya R&D yumwaka;Kugenzura iterambere ryibicuruzwa no guhindura gahunda;Shiraho ibicuruzwa byiza byubushakashatsi niterambere, kugenzura no guhugura abakozi ba tekiniki bijyanye.
Umuyobozi wa R & D: kora ibicuruzwa bishya R & D hanyuma werekane ko bishoboka gahunda;Kugenzura no gucunga iterambere nubuziranenge bwakazi;Kora ubushakashatsi ku bicuruzwa bishya kandi utange ibisubizo bifatika ukurikije ibyo umukiriya asabwa mubice bitandukanye
Abakozi & gukusanya: gukusanya no gutondekanya amakuru yingenzi;Porogaramu ya mudasobwa;Gukora ubushakashatsi, ibizamini nisesengura;Tegura ibikoresho nibikoresho byo kugerageza, kugerageza no gusesengura;Andika amakuru yo gupima, gukora ibarwa no gutegura imbonerahamwe;Kora ubushakashatsi bwibarurishamibare
2. Niki gitekerezo cyawe cyo gukora ubushakashatsi nibitekerezo byiterambere?
- Igitekerezo cyibicuruzwa no guhitamo ibicuruzwa nibisobanuro byerekana ibicuruzwa nibishushanyo mbonera byumushinga no kugerageza ibicuruzwa bitezimbere no kwemeza isoko
