描述 Description

The SY89832U is a 2.5V, high-speed, 2GHz differential LVDS (Low Voltage Differential Swing) 1:4 fanout buffer optimized for ultra-low skew applications. Within device skew is guaranteed to be less than 20ps 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 Micrel's high-speed clock synchronization family. For 3.3V applications, see SY89833L.For applications that require a different I/O combination, choose from a comprehensive product line of high-speed, low-skew fanout buffers, translators and clock generators.

簡介

SY89832U屬于集成電路（IC）的時鐘緩沖器驅(qū)動器。由制造生產(chǎn)的SY89832U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)動負載的影響而從某個信號源復制信號），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，或進行所用電信號格式轉(zhuǎn)換。
