5MHz, 3极,低通滤波器,加上消费类视频应用视频线驱动器

资料介绍
摘要: MAX4390的运算放大器配置在3杆,低通Sallen-Key滤波器,它提供了一个的-3dB带宽为5.25MHz巴特沃斯响应。该电路可用于过滤复合(CVBS)或S-视频信号在标准清晰度数字电视(SDTV )应用的视频抗锯齿和重建。该电路设计驱动一个75Ω终接,共同在视频应用的总增益为1 。

Video Applications

Abstract: The MAX4390 operational amplifier configured in a 3-pole, low-pass Sallen-Key filter that provides a
Butterworth response with a bandwidth of -3dB at 5.25MHz. This circuit can be used for video anti-aliasing and
reconstruction filtering for composite (CVBS) or S-Video signals in standard definition digital TV (SDTV)
applications. The circuit is designed to drive a 75 termination, common in video applications, with an overall
gain of 1.
