壓(ya)控(kong)(kong)(kong)(kong)晶(jing)(jing)體振(zhen)(zhen)(zhen)蕩器(qi)(qi)(qi)(qi)VCXO電(dian)參數的(de)(de)特點及選用(yong)(yong)時(shi)(shi)(shi)的(de)(de)注意事(shi)項(xiang)：1、要弄清(qing)楚具體應(ying)(ying)用(yong)(yong)場合是(shi)(shi)(shi)需要壓(ya)控(kong)(kong)(kong)(kong)晶(jing)(jing)體振(zhen)(zhen)(zhen)蕩器(qi)(qi)(qi)(qi)VCXO，還是(shi)(shi)(shi)一般的(de)(de)振(zhen)(zhen)(zhen)蕩器(qi)(qi)(qi)(qi)。當設計人員希望(wang)通(tong)過外(wai)加控(kong)(kong)(kong)(kong)制電(dian)壓(ya)來(lai)對(dui)振(zhen)(zhen)(zhen)蕩器(qi)(qi)(qi)(qi)的(de)(de)頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)作小(xiao)(xiao)范圍的(de)(de)調(diao)諧時(shi)(shi)(shi)，就應(ying)(ying)選用(yong)(yong)VCXO器(qi)(qi)(qi)(qi)件。2、頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)穩定(ding)(ding)(ding)度(du)(du)要求(qiu)：VCXO振(zhen)(zhen)(zhen)蕩頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)在工作溫度(du)(du)內是(shi)(shi)(shi)穩定(ding)(ding)(ding)的(de)(de)。當我們對(dui)VCXO進行調(diao)諧時(shi)(shi)(shi)，振(zhen)(zhen)(zhen)蕩頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)會發生改變(bian)；但偏(pian)離標稱頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)的(de)(de)各(ge)個(ge)頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)值在工作溫度(du)(du)范圍內同樣是(shi)(shi)(shi)穩定(ding)(ding)(ding)的(de)(de)。但是(shi)(shi)(shi)對(dui)于(yu)一個(ge)給定(ding)(ding)(ding)的(de)(de)頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)而言，頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)穩定(ding)(ding)(ding)度(du)(du)要求(qiu)越高，要得到大(da)范圍的(de)(de)牽引度(du)(du)就越困難。采(cai)用(yong)(yong)全硅MEMS不能獲得良好的(de)(de)頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)穩定(ding)(ding)(ding)度(du)(du)。這是(shi)(shi)(shi)因(yin)為硅存在顫動(dong)噪(zao)聲和相位噪(zao)聲所致。VCXO采(cai)用(yong)(yong)了(le)石英晶(jing)(jing)體，頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)異常穩定(ding)(ding)(ding)，是(shi)(shi)(shi)目(mu)前(qian)很好的(de)(de)頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)控(kong)(kong)(kong)(kong)制器(qi)(qi)(qi)(qi)件。3、電(dian)壓(ya)調(diao)諧與頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)變(bian)化(hua)的(de)(de)關系：VCXO的(de)(de)頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)偏(pian)移值同加在其(qi)調(diao)諧電(dian)路(lu)上的(de)(de)控(kong)(kong)(kong)(kong)制電(dian)壓(ya)的(de)(de)大(da)小(xiao)(xiao)有關。VCXO標稱頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)對(dui)應(ying)(ying)的(de)(de)調(diao)諧電(dian)壓(ya)規(gui)定(ding)(ding)(ding)為VCC（電(dian)源電(dian)壓(ya)）的(de)(de)一半。VCC為5V的(de)(de)VCXO，控(kong)(kong)(kong)(kong)制電(dian)壓(ya)為2.5V時(shi)(shi)(shi)就產生中心頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)。控(kong)(kong)(kong)(kong)制電(dian)壓(ya)為（0.5～4.5）V的(de)(de)VCXO，其(qi)頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)變(bian)化(hua)曲線的(de)(de)斜率(lv)(lv)(lv)(lv)為正。也就是(shi)(shi)(shi)說，當控(kong)(kong)(kong)(kong)制電(dian)壓(ya)從2.5V上升為4.5V時(shi)(shi)(shi)，振(zhen)(zhen)(zhen)蕩器(qi)(qi)(qi)(qi)的(de)(de)頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)將(jiang)增大(da)；當控(kong)(kong)(kong)(kong)制電(dian)壓(ya)從2.5V降為0.5V時(shi)(shi)(shi)，振(zhen)(zhen)(zhen)蕩器(qi)(qi)(qi)(qi)的(de)(de)頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)將(jiang)減小(xiao)(xiao)。杭州晶(jing)(jing)體振(zhen)(zhen)(zhen)蕩器(qi)(qi)(qi)(qi)用(yong)(yong)途品質至上，價格親民，交(jiao)期保障，成都晶(jing)(jing)寶值得信賴！
