AD9511屬于集成電路（IC）的時鐘緩沖器驅(qū)動器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD9511時鐘緩沖器，驅(qū)動器時鐘緩沖器和驅(qū)動器集成電路產(chǎn)品族中的產(chǎn)品用于幫助信號在系統(tǒng)中傳輸，常用作頻率/時間參考信號，以同步系統(tǒng)內(nèi)的活動。盡管這些器件最常用到的功能就是緩沖（即，為使信號不受驅(qū)動負(fù)載的影響而從某個信號源復(fù)制信號），但是該產(chǎn)品族中的某些器件還能執(zhí)行其他功能，例如選擇性改變緩沖信號路徑、按某個整數(shù)值分割信號頻率，或進(jìn)行所用電信號格式轉(zhuǎn)換。

GENERAL DESCRIPTION

The AD9511 provides a multi-output clock distribution function along with an on-chip PLL core. The design emphasizes low jitter and phase noise to maximize data converter performance. Other applications with demanding phase noise and jitter requirements also benefit from this part.
