100 MHz High-Ukuzinza, Phansi-Isigaba-I-Noise VCTCXO

Imvamisa Ezinzile · Umsindo Wesigaba Esiphansi · I-Precision Electronic Tuning{0}}Ihlinzeka Ngezithenjwa Ezithembekile Zewashi ze-5G Base Stations, I-Microwave Communications, kanye Nezisetshenziswa Zokuhlola

Ezimisweni zesimanje zokuxhumana, iwashi lenkomba linendima efana neyenhliziyo yomuntu. Inquma ngokuqondile ukunemba kwemvamisa, ukuzinza kwenkampani yenethiwekhi, ubumsulwa besignali, nokusebenza kokuvumelanisa kwesistimu. Ikakhulukazi ezimeni ezifana nokuxhumana kwe-5G/wireless, i-microwave backhaul, kanye{3}}nokudluliswa kwedatha ngesivinini esiphezulu, ukuzinza okuphezulu kwefrikhwensi nomsindo wesigaba esiphansi kuyisihluthulelo sokunciphisa i-jitter yewashi lesistimu, ukunciphisa amazinga amaphutha, kanye nokuthuthukisa ukusebenza kwesixhumanisi se-RF.

Namuhla, sethula i-US14S6-100.000- 50NQDT0Q, i-VCTCXO engu-100 MHz evela e-Hangjing (HCI) edizayinelwe ngokukhethekile{4}}izinto zokuxhumana ezisebenza kahle. Ukuhlanganisa ukuzinza okuphezulu, umsindo wesigaba esiphansi, nobubanzi bokushuna okubanzi, kuyisixazululo esithandwayo sereferensi yefrikhwensi yokuxhumana.

01｜Kungani Aphezulu{1}Ama-VCTCXO Okusebenza Abalulekile Ezinhlelweni Zokuxhumana?

Ukunemba kwemvamisa kuthinta ukuvumelanisa inkampani yenethiwekhi kanye nekhwalithi yokwehlisa

Umsindo wesigaba wehlisa ukuhlanzeka kokubukeka futhi ukhuphule -ukuphazamiseka kwesiteshi

Ukuzinza kwezinga lokushisa kunquma ukwethembeka kwemishini ezindaweni ezingaphandle eziyinkimbinkimbi

Amandla okushuna kagesi asiza ukukhiya kwe-PLL kanye ne-AFC (Ukulawula Imvamisa Okuzenzakalelayo)

I-VCTCXO enhle kakhulu ihlinzeka ngomthombo wefrikhwensi ohlanzekile, ozinzile, nolawulekayo we-RF ngaphambili-ekugcineni,{1}}okukhiyiwe kwesigaba-(PLLs), ama-oscillator circuits,{2}}namawashi edatha anesivinini esiphezulu.

02｜Amamethrikhi Okusebenza Okubalulekile Okuhlanu: Uhlolojikelele Olubanzi Lwamakhono Awo Aqinile

① ±0.5 ppm Ukuzinza Okuphezulu

Izinga Lokushisa Lokusebenza: -40℃ukuya ku-+85 degree

Ukuzinza-okugcwele-kwebanga lokushisa: ±0.5 ppm

Iphatha kalula-izimo zezinga lokushisa ezibanzi njengeziteshi eziyisisekelo nezinto zokusebenza zangaphandle

② Ultra-Umsindo Wesigaba Esiphansi (Okuvamile ngo-100 MHz)

Umsindo wesigaba esiphansi=i-spectrum ehlanzekile + i-jitter yewashi eliphansi, ethuthukisa ngokuqondile ikhwalithi yesixhumanisi sokuxhumana.

③ ±6 ppm ububanzi bokushuna

I-voltage yokulawula: 0–5 V (i-voltage emaphakathi: 2.5 V)

Ifanele ukukhiya imvamisa ye-PLL, i-AFC (Automatic Frequency Control), ukulinganisa imvamisa, kanye nesinxephezelo se-offset yesistimu

④ +7 i-dBm sine wave okukhiphayo

Amandla okukhiphayo angu-+7 dBm ekulayisheni okungu-50 Ω

I-sine waveform evamile, efanelana ngokuphelele ne-RF kanye{0}}nezixhumanisi zewashi ezisebenza kahle

⑤ Iphakheji elihlanganisiwe elingu-14×9 mm

Iphakethe lensimbi le-6-pad SMD, ukusebenza kokuvikela okulinganisa kanye nokusetshenziswa kwesikhala se-PCB

Ifanele-imiklamo yezinga eliphezulu{1}}ezisetshenziswa zokuxhumana

Ukusebenza okuphezulu-I-VCTCXO ihlinzeka ngosekelo oluzinzile, oluhlanzekile lwaso sonke isixhumanisi sokuxhumana ukusuka phezulu kuye phansi.

05｜Ukucaciswa Okubalulekile Ngokubuka nje

06｜ Isifinyezo

I-Hangjing 100 MHz VCTCXO, enokuzinza okuphezulu okungu-±0.5 ppm, i-ultra-isigaba esiphansi somsindo we--165 dBc/Hz, i-electronic tuning range engu-±6 ppm, kanye ne-sine wave ephumayo ye-+7 dBm, inikeza amasistimu okulawula okuzinzile, imvamisa, ireferensi ye-RF elandelayo, okokusebenza kanye nokunemba izinsimbi zokuhlola.

Kungakhathaliseki ukuthi kuseziteshini eziyisisekelo, ukuxhumana kwe-microwave nesathelayithi, noma-amanethiwekhi anesivinini esikhulu kanye nezinhlelo zokusebenza zokuhlola nokulinganisa,{1}}ifaneleka kahle ukusebenza "njengenhliziyo yefrikhwensi."

I-Hangjing VCTCXO - Ihlinzeka ngereferensi yefrikhwensi ezinzile futhi emsulwa yezinhlelo zokuxhumana.
