FAQ
I-Q1: Indlela yokugqiba ngokukhawuleza ukuba usebenzise uluhlu oluncinci okanye olubanzi lweqondo lokushisa xa ukhetha uluhlu lweqondo lokushisa?
A: Qwalasela indawo yokusebenza yesixhobo. Kwiimveliso zombane eziqhelekileyo zangaphakathi (umzekelo, izithethi zeBluetooth), khetha imodeli yoluhlu lobushushu emxinwa (-20 ~ +70 isidanga). Iimoto, izixhobo zangaphandle, okanye ezinye iimeko ezinotshintsho olubalulekileyo lobushushu, beka phambili uguqulelo olubanzi lobushushu (-40 ~ +85 isidanga).
I-Q2: Lithetha ukuthini izinga lokuguga le-crystal oscillator, kwaye ngaba sifanele sikhathazeke ngayo?
A: Ibhekisa kuluhlu lokutenxa rhoqo ngonyaka. Izinga lokuguga le-3ppm/ngonyaka alinamsebenzi{2}}izixhobo eziqhelekileyo zingasebenza iminyaka ngaphandle kweempazamo ezibonakalayo. Kwizixhobo ezichaneke kakhulu-eziphezulu{5}, ulungelelwaniso oluqhelekileyo lwanele.
I-Q3: Indlela yokukhetha umthamo womthwalo kwiinketho ezikhoyo ze-7pF / 9pF / 12.5pF?
A: Khetha ngokusekelwe kwiimfuno zoyilo lwesekethe. Bhekisela kwincwadana yezixhobo okanye uqhagamshelane nathi kwangaphambili ukuze uqinisekise ukuhambelana komthamo womthwalo, uqinisekisa imveliso ezinzileyo yefrikhwensi evela kwi-crystal oscillator.
