ADN4670BSTZ-REEL7集成电路（IC）的时钟缓冲器驱动器规格书PDF中文资料

ADN4670BSTZ-REEL7属于集成电路（IC）的时钟缓冲器驱动器。由亚德诺半导体技术有限公司制造生产的ADN4670BSTZ-REEL7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。

GENERAL DESCRIPTION

The ADN4670 is a low voltage differential signaling (LVDS) clock driver that expands a differential clock input signal to 10 differential clock outputs. The device is programmable using a simple serial interface, so that one of two clock inputs can be selected (CLK0/CLK0 or CLK1/CLK1) and any of the differential outputs (Q0/Q0 to Q9/Q9) can be enabled or disabled (tristated). The ADN4670 is designed for use in 50 Ω transmission line environments.

When the enable input EN is high, the device may be programmed by clocking 11 data bits into the shift register. The first 10 bits determine which outputs are enabled (0 = disabled, 1 = enabled), while the 11th bit selects the clock input (0 = CLK0, 1 = CLK1). A 12th clock pulse transfers data from the shift register to the control register.

The ADN4670 is fully specified over the industrial temperature range and is available in a 32-lead LFCSP and LQFP packages.
