FCX9M02500020Y5L 49SMD 25M 20PF 日本富士FCom晶振參數(shù)對(duì)比
FCX9M02500020Y5L 49SMD 25M 20PF 日本富士FCom晶振參數(shù)對(duì)比
測(cè)試友商的49S/24M20pF20ppm、49S/8M20pF20ppm、49S/16M20pF20ppm的參數(shù),各5件.具體測(cè)試數(shù)據(jù)如下:隨機(jī)選擇FCom的相同頻率,日本富士晶體晶振相同的標(biāo)稱參數(shù)測(cè)試所示.
結(jié)果發(fā)現(xiàn)友商的頻率通常是負(fù)的.雖然友商標(biāo)稱±20ppm的產(chǎn)品精度符合標(biāo)準(zhǔn),但一般控制在±10ppm以上,有的高達(dá)±18ppm,這對(duì)于FCom來說已經(jīng)是不合格產(chǎn)品了.標(biāo)稱±20ppm的FCom產(chǎn)品精度一般控制在±10ppm以內(nèi).
同時(shí)友商產(chǎn)品的DLD2值過大.DLD2值是測(cè)試晶振在運(yùn)行過程中的最大電阻值和最小電阻值之間的差值.具體反應(yīng)是晶振與IC諧振時(shí)電阻值的變化,功率在0.01μW到100μW之間.如果晶振的DLD2值過大,晶振可能會(huì)在運(yùn)行過程中停止振蕩.例如,友商的一款產(chǎn)品的DLD2值達(dá)到了5.7歐姆,說明晶振的電阻值不穩(wěn)定,產(chǎn)品的一致性不夠.FCom產(chǎn)品的DLD2值都在1歐姆以內(nèi),比友商的產(chǎn)品更加一致

此外友商晶振的FDLD2值過大.FDLD2值反映了晶振與IC諧振時(shí)頻率輸出的穩(wěn)定性.參數(shù)值越小越好.該值越小,有源晶振頻率越穩(wěn)定.FCom晶振的FDLD2值均設(shè)置在2ppm以內(nèi).
DLD2值和FDLD2較大的主要原因如下:
一.晶片材料問題,如晶片上的亮點(diǎn)雜質(zhì).
二.晶振廠在生產(chǎn)過程中對(duì)晶片的表面處理并不純凈.
三.當(dāng)晶振在密封焊接時(shí),內(nèi)部有水分.

比較兩個(gè)品牌使用的材料,FCom的49S晶體振蕩器外殼使用二次氧化光亮外殼,在生產(chǎn)過程中的49S晶振檢查顯示其外殼采用啞光工藝.從成本角度來看,二次氧化處理的光亮外殼成本略高,但保質(zhì)期更長(zhǎng).特別是晶振在大氣環(huán)境中使用時(shí),晶振的表面可以保持光滑,長(zhǎng)時(shí)間不氧化,而啞光外殼更容易氧化.
從以上可以看出,FCom貼片晶振的產(chǎn)品在生產(chǎn)過程中使用更純凈的晶片原材料,生產(chǎn)工藝更先進(jìn),防止晶片在生產(chǎn)過程中受到水分污染.產(chǎn)品的一致性高于其他競(jìng)爭(zhēng)對(duì)手的產(chǎn)品.此外,FCom還考慮了產(chǎn)品的可靠性和耐用性.此外,FCom還考慮了產(chǎn)品的可靠性和耐用性.它在產(chǎn)品外殼上使用更耐用的二次氧化工藝,以加長(zhǎng)產(chǎn)品的使用壽命.
