Iimpawu zeMveliso
■ Ukuchaneka okuphezulu kunye noZinzo oluPhezulu{0}}Uzinzo oluPhezulu:
- Ihambisa ukuchaneka okuphezulu kwe-± 7ppm kunye ne-Ultra - ukuzinza okuphezulu kwi-54MHz.
■ Ubungakanani obuncinci kakhulu:
- Iqhayisa nge-ultra - encinci ye-2.0 × 1.6mm yefom factor, ibe yi-SMD passive crystal oscillator.
Usetyenziso
- ICrystal ka-2016 yenza ukuba i-motherboard edibeneyo kunye noyilo oluphathwa ngesandla, ikristale ihambisa ixesha elichanekileyo le-RTC yonxibelelwano lwe-5G, unxibelelwano lweselula.

FAQ
I-Q1: Uthini umahluko phakathi "kweqondo lokushisa elisebenzayo" kunye "noluhlu lweqondo lokushisa lokugcina" lwe-crystal oscillator?
A: Uluhlu lobushushu obusebenzayo: Uluhlu lobushushu apho isixhobo sisebenza ngesiqhelo (umzekelo, -40℃ukuya +85 degree).
Uluhlu lwamaqondo obushushu: Uluhlu lobushushu isixhobo sinokumelana naso xa singaqhutywanga (ngokuqhelekileyo banzi, umzekelo, -55℃ukuya +125 degree).
Q2: Kutheni icrystal oscillator inokusilela kwindawo{1}} yokufuma okuphezulu?
A: Ukufuma kunokubangela i-corrosion yensimbi yangaphakathi okanye i-electrode oxidation ngaphakathi kwepakethe, ekhokelela kwi-frequency drift okanye ukusilela okupheleleyo kwe-oscillation. Kucetyiswa ukuba kusetyenziswe intsimbi etywiniweyo okanye iipakethi ze-ceramic ukuthembeka okungcono.
I-Q3: Kutheni ezinye ii-crystal oscillators zifuna "imbuyekezo yokuguga"?
A: I-Crystal oscillators ifumana i-frequency drift ngokuhamba kwexesha (isiphumo sokuguga). -usetyenziso oluphezulu (umzekelo, unxibelelwano lwesathelayithi) lufuna imbuyekezo yesekethe eguqukayo ukuze kugcinwe ukuchaneka.
