HMC744LC3集成电路（IC）的时钟缓冲器驱动器规格书PDF中文资料

HMC744LC3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HMC744LC3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 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.
