CXVD3321是一个集成了三倍6dB增益的视频缓冲区轨对轨输出驱动器及三级六阶输出重构
滤波器，拥有35MHz-3dB带宽。与无源LC相比过滤器和离散驱动程序，CXVD3321可以改善图像质量。以及它非常适合电池供电的应用，因为CXVD3321可以在单电源范围内运行
从+3.3V到+5.5V，接收超低36mA静态电流。视频信号，例如DAC的输出，可以输入到CXVD3321中采用直流或交流耦合方式。内部二极管夹和偏置电路如果需要交流耦合输入，可以使用。CXVD3321还集成了内部电平移位电路，避免同步脉冲被截断，并允许数据耦合输出。CXVD3321中的驱动器可以驱动直流或交流耦合的单（150Ω）或双（75Ω）负载。

一.产品概述
The CXVD3321 is a video buffer which integrates triple 6dB Gain rail-to-rail output driver and triple 6th order output reconstruction filter, and it owns 35MHz -3dB bandwidth. Compared with passive LC
filters and discrete drivers, CXVD3321 can improve image quality. And it is ideally suited for battery powered applications, because the CXVD3321 can operate under the environment with single supplies ranging
from +3.3V to +5.5V and sinking an ultra-low 36mA quiescent current. Video signal, such as the output of DAC, can be input in the CXVD3321 by DC-coupled or AC-coupled ways. Internal diode clamps and bias circuitry may be used if AC-coupled inputs are required. CXVD3321 also integrates an internal level shift circuit which avoids sync-pulse being clipped and allows DCcoupled output. The driver in CXVD3321 can drive DC or AC-coupled single (150Ω) or dual (75 Ω) loads.
