CXVD3397低电压、四通道视频滤波器旨在用低成本的集成设备取代无源LC滤波器和驱动器。与典型的2阶或3阶无源LC滤波器相比，6阶滤波器提供了更高的图像质量。这种滤波器特别适用于高清晰度视频信号，如电视和机顶盒应用。CXVD3397可以由直流耦合DAC输出或交流耦合信号直接驱动。如果需要交流耦合输入，可以使用内部二极管夹和偏置电路。输出可驱动交直流耦合的单（150Ω）或双（75Ω）负载。直流耦合输出消除了输出耦合电容的需要。输入直流电平在输出端偏移约380mV。

The CXVD3397 low voltage, four channels video filter is intended to replace passive LC filter and drivers with a low-cost integrated device. The 6th order filter provides much improved image quality compared to typical 2 nd or 3rd order passive LC filters. The filters are especially suited for high definition video signals, such as television and set-top box applications. The CXVD3397 can be directly driven by a DC coupled DAC output or an AC coupled signal. Internal diode clamps and bias circuitry may be used if AC-coupled inputs are required. The output can drive AC or DC coupled single (150Ω) or dual (75Ω) loads. DC coupling the outputs removes the need for output coupling capacitors. The input DC levels are offset approximately 380 mV at the output.
