视频放大器，4 沟道，带可选择 SD/HD 重构滤波器
Obsolete
概览
NCS2564 是一款 4 沟道高速视频驱动器，每个沟道上均带 6 阶 Butterworth 重构滤波器。前三个沟道具有可选择的标清 (SD)/高清 (HD) 滤波器，每个沟道一个。第四个沟道提供一个额外的滤波器驱动器，用于驱动 CVBS 型视频信号。实际上 NCS2564 是 SD/HD 三视频驱动器与 CVBS 单视频驱动器的组合。它可兼容大多数视频处理器中嵌入的数字-模拟转换器 (DAC)。为了进一步降低功耗，提供了两个启用引脚，一个用于三驱动器，另一个用于单驱动器。一个引脚用于选择三驱动器的滤波器频率。所有沟道均可接受直流或交流耦合信号。如果为交流耦合，则启用内部箝位。输出可驱动交流或直流耦合 150 Ω 负载。
