描述 Description

The ZL40226 is an LVDS clock fanout buffer with eight identical output clock drivers capable of operating at frequencies up to 750MHz.The two Inputs to the ZL40226 are externally terminated to allow use of precision termination components and to allow full flexibility of input termination. The ZL40226 can accept DC coupled LVPECL or LVDS and AC coupled LVPECL, LVDS, CML or HCSL input signals; single ended input signals can also be accepted. A pin compatible device with internal termination is also available.The ZL40226 is designed to fan out low-jitter reference clocks for wired or optical communications applications while adding minimal jitter to the clock signal. An internal linear power supply regulator and bulk capacitors minimize additive jitter due to power supply noise. The device operates from 2.5V+/-5% or 3.3V+/-5% supply. It's operation is guaranteed over the industrial temperature range -40°C to +85°C.

簡介

ZL40226屬于集成電路（IC）的時(shí)鐘緩沖器驅(qū)動(dòng)器。由制造生產(chǎn)的ZL40226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。
