SY89832U集成電路（IC）的時(shí)鐘緩沖器驅(qū)動(dòng)器規(guī)格書PDF中文資料

SY89832U屬于集成電路（IC）的時(shí)鐘緩沖器驅(qū)動(dòng)器。由微芯科技股份有限公司制造生產(chǎn)的SY89832U時(shí)鐘緩沖器，驅(qū)動(dòng)器時(shí)鐘緩沖器和驅(qū)動(dòng)器集成電路產(chǎn)品族中的產(chǎn)品用于幫助信號(hào)在系統(tǒng)中傳輸，常用作頻率/時(shí)間參考信號(hào)，以同步系統(tǒng)內(nèi)的活動(dòng)。盡管這些器件最常用到的功能就是緩沖（即，為使信號(hào)不受驅(qū)動(dòng)負(fù)載的影響而從某個(gè)信號(hào)源復(fù)制信號(hào)），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(hào)路徑、按某個(gè)整數(shù)值分割信號(hào)頻率，或進(jìn)行所用電信號(hào)格式轉(zhuǎn)換。

General Description

The SY89832U is a 2.5V, high-speed, 2 GHz

differential, low voltage differential swing (LVDS)

1:4 fanout buffer optimized for ultra-low skew

applications. Within device skew is guaranteed to be

less than 20 ps over supply voltage and temperature.

The differential input buffer has a unique internal

termination design that allows access to the

termination network through a VT pin. This feature

allows the device to easily interface to different logic

standards. A VREF–AC reference output is included for

AC-coupled applications.

The SY89832U is a part of the high-speed clock

synchronization family. For 3.3V applications, see

SY89833L or SY89833AL.
