振蕩器頻率上變頻器

AD9552是一款小數(shù)N分頻、基于鎖相環(huán)(PLL)的時(shí)鐘發(fā)生器，專為取代高頻晶體振蕩器和諧振器而設(shè)計(jì)。該器件采用Σ-Δ調(diào)制器(SDM)來處理小數(shù)頻率合成。用戶將單端時(shí)鐘信號直接與REF引腳相連，或者在XTAL引腳上連接一個(gè)晶體諧振器，即可提供輸入?yún)⒖夹盘?。\n\n AD9552為引腳可編程器件，根據(jù)8種常用輸入頻率的其中一種頻率，可提供64種標(biāo)準(zhǔn)輸出頻率中的一種頻率。該器件還有一個(gè)三線式SPI接口，用戶可以通過該接口自定義設(shè)置輸入與輸出頻率比。\n\n AD9552需用外部電容來構(gòu)成PLL的環(huán)路濾波器。雖然AD9552嚴(yán)格按照CMOS工藝制造，但其輸出與LVPECL、LVD ? 將低頻輸入?yún)⒖夹盘栟D(zhuǎn)換為高頻輸出信號\n\n? 輸入頻率范圍：6.6 MHz至125 MHz\n\n? 輸出頻率最高達(dá)900 MHz\n\n? 預(yù)設(shè)引腳可編程頻率轉(zhuǎn)換比;
