HMC744LC3集成電路（IC）的時鐘緩沖器驅(qū)動器規(guī)格書PDF中文資料

HMC744LC3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HMC744LC3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(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，或進行所用電信號格式轉(zhuǎn)換。

General Description

The HMC744LC3 is a 1:2 Fanout Buffer designed to support data transmission rates up to 14 Gbps, and clock frequencies as high as 14 GHz.

All differential inputs to the HMC744LC3 are CML and terminated on-chip with 50 Ohms to the positive supply, Vcc, and may be AC or DC coupled. The differential CML outputs are source terminated to 50 Ohms and may also be AC or DC coupled. Outputs can be connected directly to a 50 Ohm Vcc-terminated system, while DC blocking capacitors may be used if the terminating system is 50 Ohms to ground. The HMC744LC3 also features an output level control pin, VR, which allows for loss compensation or signal-level optimization. the HMC744LC3 operates from a single 3.3 V supply and is available in ROHS-compliant 3x3 mm SMT package.
