NB6LQ572中文资料NB6LQ572: Input Mux - 4:1 Differential, 2.5 V / 3.3 V, with Input Equalizer, Clock / Data Fanout Buffer - 1:2 LVPECL数据手册ONSEMI规格书

描述 Description

The NB6LQ572 is a high performance differential 4:1 Clock/Data input multiplexer and a 1:2 LVPECL Clock / Data fanout buffer that operates up to 5 GHz / 6.5Gbps respectively with a 2.5V or 3.3V power supply. Each INx / INxb input pair incorporates a fixed Equalizer Receiver, whichwhen placed in series with a Clock / Data path, will enhance the degraded signal transmitted across an FR4 backplane or cable interconnect. For applicationsthat do not require Equalization, consider the NB7L572, which is pin-compatible to the NB6LQ572. The differential Clock / Data inputs have internal 50-ohm termination resistors and will accept differential LVPECL, CML, or LVDS logic levels. The NB6LQ572 incorporates a pair of Select pins that will choose one of four differential inputs and will produce two identical LVPECL output copies ofClock or Data.As such, the NB6LQ572 is ideal for SONET, GigE, Fiber Channel, Backplane and other Clock/Data distribution applications. The two differential LVPECL outputs will swing 750mV when externally loaded and terminated with a50-ohm resistor to VCC-2V and are optimized for low skew and minimal jitter. The NB6LQ572 is offered in a low profile 5x5mm 32-pin QFN Pb-free package. Application notes, models, and support documentation are available at www.onsemi.com. The NB6LQ572 is a member of the ECLinPS MAX family of high performance clock products.

简介

NB6LQ572属于集成电路（IC）的时钟缓冲器驱动器。由制造生产的NB6LQ572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。
