ZL40218中文资料Precision 1:8 LVDS Buffer数据手册Microchip规格书

描述 Description

The ZL40218 is an LVDS clock fanout buffer with eight identical output clock drivers capable of operating at frequencies up to 750MHz.Inputs to the ZL40218 are externally terminated to allow use of precision termination components and to allow full flexibility of input termination. The ZL40218 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 ZL40218 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. Its operation is guaranteed over the industrial temperature range -40°C to +85°C.

简介

ZL40218属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的ZL40218时钟缓冲器，驱动器时钟缓冲器和驱动器集成电路产品族中的产品用于帮助信号在系统中传输，常用作频率/时间参考信号，以同步系统内的活动。尽管这些器件最常用到的功能就是缓冲（即，为使信号不受驱动负载的影响而从某个信号源复制信号），但是该产品族中的某些器件还能执行其他功能，例如选择性改变缓冲信号路径、按某个整数值分割信号频率，或进行所用电信号格式转换。
