KX3213D0032.768000是標(biāo)準(zhǔn)的計時參考方案
在晶振行業(yè)里，我們最常聽到客戶采購的晶振頻率就是32.768KHZ。由此可見32.768K是最常用的頻率，32.768KHZ是一個標(biāo)準(zhǔn)的頻率，晶振頻率的應(yīng)用主要有以下幾個方面的參數(shù)：尺寸、負(fù)載電容、頻率偏差、應(yīng)用范圍。
一般用于計時,現(xiàn)代的我們一樣離不開時間鐘表，而32.768K是一個很有意義的數(shù)字，是我們每天都要用到它，它給我們帶來太多的好處。
亞陶晶振KX31Q系列，實時時鐘振蕩器在廣泛的工作條件下實現(xiàn)了極好的穩(wěn)定性，電源電壓：1.8/2.5/3.3V超低電流、頻率：32.768KHz、汽車級CMOS有源晶體振蕩器，四腳貼片晶振，穩(wěn)定性：20PPM到50PPM，它利用 Pericom專有技術(shù)實現(xiàn)低于 15μA的超低電流。輸出時鐘信號與 LVCMOS/LVTTL 邏輯電平兼容。該器件采用卷帶包裝，小體積尺寸采用3.2x2.5mm表面貼裝陶瓷封裝。

無論是智能手機(jī)，電腦平板，還是智能手表，你都可以看到時鐘總是那樣不緊不慢有規(guī)律的一秒一秒的走下去。為什么所有時鐘都能保持同樣的頻率一秒秒的走下去，每一秒都不會更快或更慢呢？
主要是32.768k時鐘晶振的作用，等于2的15次方，即1秒。我們每天用的手表、手機(jī)、電腦上顯示作用的鐘就是由它演變過來的。
