Imodeli yeZhongweiI-PCM3360Q iyisiguquli esisebenza kahle kakhulu somsindo we-analog-to-digital (ADC) esisetshenziswa kakhulu ezinhlelweni zomsindo wemoto. Ineziteshi ze-ADC eziyisi-6, ingakwazi ukucubungula amasiginali wokufakwa kwe-analog, futhi isekele okokufaka okuhlukile okufika ku-10VRMS. Ngaphezu kwalokho, i-chip ihlanganisa ukuchema kwe-microphone okuhlelekayo kanye nemisebenzi yokuhlonza okokufaka, iyenze ithembeke kakhulu futhi iguquguquke ezinhlelweni zezimoto.
Mayelana nokusebenza komsindo, i-PCM3360Q inokusebenza okuhle kakhulu kwe-ADC, enobubanzi obushintshashintshayo bokuhlukanisa komugqa obungu-110dB, uhla oluguquguqukayo lokufakwa kwemakrofoni elingu-110dB, kanye nokuhlanekezela okuphelele kwe-harmonic kanye nomsindo (THD+N) ka -94dB. Lawa mapharamitha abonisa ukuthi anganikeza ukucaca okuphezulu kakhulu namazinga omsindo aphansi ngesikhathi sokuguqulwa komsindo.
Mayelana nokusetshenziswa kwamandla, i-PCM3360Q idla ngaphansi kuka-21.5mW/isiteshi ku-48kHz, okwenza ifaneleke kakhulu izinhlelo zokusebenza zezimoto ezidinga ukusebenza kwamandla aphansi. Izinga lokushisa elisebenzayo lingu -40°C kuya ku-125°C, futhi lihlangabezana nezinga le-AEC-Q100, liqinisekisa ukusebenza okuzinzile ezindaweni ezahlukene.
I-PCM3360Q isekela i-time division multiplexing (TDM), i-I2S noma amafomethi omsindo abhalansile kwesokunxele (LJ) futhi ilawulwa nge-I2C noma i-SPI interface. Lokhu kuvumela ukuthi ihlanganiswe kalula ezinhlobonhlobo zezinhlelo zomsindo wemoto futhi ixhumane ngaphandle komthungo namanye amadivaysi omsindo.
Imodeli ye-Zhongwei i-PCM3360Q iyisinqumo esifanele sezinhlelo zomsindo wemoto ezinekhwalithi ephezulu yomsindo, ukusetshenziswa kwamandla aphansi nezindlela zokulawula ezivumelana nezimo, futhi ingahlangabezana nezindinganiso eziphakeme zezimoto zesimanje zezinhlelo zomsindo.
Imodeli ye-Zhongwei PCM3360Q isetshenziswa kakhulu ezimeni ezifana nezinhlelo zomsindo wemoto, okomsindo wasekhaya kanye nemishini yevidiyo, kanye nemishini yomsindo echwepheshile. Lezi zimo zohlelo lokusebenza zisebenzisa ngokugcwele ukusebenza kwayo okuphezulu, ukusetshenziswa kwamandla okuphansi, nezindlela zokulawula ezivumelana nezimo ukuze kuhlinzekwe umuzwa womsindo wekhwalithi ephezulu emikhakheni ehlukahlukene. Okulandelayo ukuhlaziya nencazelo enemininingwane:
