CDCLVP110集成电路（IC）的时钟缓冲器驱动器规格书PDF中文资料

CDCLVP110属于集成电路（IC）的时钟缓冲器驱动器。由德州仪器制造生产的CDCLVP110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。

DESCRIPTION

The CDCLVP110 clock driver distributes one

differential clock pair of either LVPECL or HSTL

(selectable) input, (CLK0, CLK1) to ten pairs of

differential LVPECL clock (Q0, Q9) outputs with minimum skew for clock distribution. The

CDCLVP110 can accept two clock sources into an

input multiplexer. The CLK0 input accepts either

LVECL/LVPECL input signals, while CLK1 accepts an

HSTL input signal when operated under LVPECL

conditions. The CDCLVP110 is specifically designed

for driving 50-Ω transmission lines.

The VBB reference voltage output is used if

single-ended input operation is required. In this case

the VBB pin should be connected to CLK0 and

bypassed to GND via a 10-nF capacitor.

However, for high-speed performance up to 3.5 GHz,

the differential mode is strongly recommended.

The CDCLVP110 is characterized for operation from

–40°C to 85°C.
