Incazelo ye-PCM1690
Idivayisi ye-PCM1690 iyi-high-performance, i-single-chip, i-24-bit, ishaneli eyisishiyagalombili, i-audio digital-to-analog converter (DAC) enemiphumela ehlukile.Ishaneli eyisishiyagalombili, i-24-bit DAC isebenzisa imodulator ethuthukisiwe, enamazinga amaningi e-delta-sigma (ΔΣ) futhi isekela izilinganiso zesampula ezingu-8-kHz kuya ku-192-kHz kanye nedijithali yobubanzi obuyi-16-/20-/24-/32-bit. igama lokufakwayo komsindo kusixhumi esibonakalayo somsindo.I-interface yomsindo ye-PCM1690 isekela ifomethi ye-time-division-multiplexed (TDM) ngaphezu kwe-I evamile2S, alungiselwe kwesokunxele, afaneleke kwesokudla, kanye namafomethi e-DSP.
I-PCM1690 ingalawulwa ngocingo olunezintambo ezintathu, isixhumi esibonakalayo esihambisana ne-SPI, noma izintambo ezimbili, I.2I-serial interface ehambisana ne-C ku-software, enikeza ukufinyelela kuyo yonke imisebenzi ehlanganisa ukuncishiswa kwedijithali, ukuthulisa okuthambile, ukungagxili, nokunye.Futhi, imodi yokulawula izingxenyekazi zekhompuyutha inikeza isethi engaphansi yemisebenzi ehlelekayo yomsebenzisi ngokusebenzisa izikhonkwane zokulawula ezimbili.I-PCM1690 itholakala kuphakheji ye-HTSSOP-48 engu-12-mm × 8-mm (12-mm × 6-mm umzimba)
Kuwo wonke amaphakheji atholakalayo, bheka isengezo esihlelekayo ekupheleni kweshidi ledatha.
1. Obani abasebenzi bomnyango wakho we-R & D?Yiziphi iziqu zakho?
-R & D Umqondisi: yenza uhlelo lwesikhathi eside lwe-R & D lwenkampani futhi babambe isiqondiso socwaningo nentuthuko;Qondisa futhi uqondise umnyango we-r&d ukuze usebenzise isu le-r&d lenkampani kanye nohlelo lonyaka lwe-R&D;Lawula inqubekelaphambili yokuthuthukiswa komkhiqizo futhi ulungise uhlelo;Misa ithimba locwaningo lomkhiqizo elihle kakhulu nelokuthuthukisa, abacwaningi mabhuku kanye nokuqeqeshwa okuhlobene nabasebenzi bezobuchwepheshe.
Umphathi we-R & D: yenza uhlelo olusha lwe-R & D futhi ubonise ukuthi kungenzeka uhlelo;Ukugada nokuphatha inqubekelaphambili kanye nekhwalithi yomsebenzi we-r&d;Cwaninga ukuthuthukiswa komkhiqizo omusha futhi uphakamise izixazululo ezisebenzayo ngokuvumelana nezidingo zamakhasimende emikhakheni ehlukene
Abasebenzi be-R&d: baqoqa futhi balungise idatha ebalulekile;Uhlelo lwekhompyutha;Ukwenza izivivinyo, izivivinyo kanye nokuhlaziya;Lungiselela izinto zokwakha kanye nezinto zokusebenza zokuhlola, izivivinyo nokuhlaziya;Rekhoda idatha yokulinganisa, yenza izibalo futhi ulungiselele amashadi;Yenza izinhlolovo zezibalo
2. Uthini umbono wakho wocwaningo nokuthuthukiswa komkhiqizo?
- Ukwakhiwa komkhiqizo kanye nomqondo wokukhethwa komkhiqizo kanye nokuhlolwa kwencazelo yomkhiqizo kanye nomklamo wepulani yephrojekthi kanye nokuthuthukiswa kokuhlolwa komkhiqizo kanye nokwethulwa kokuqinisekisa emakethe
