三通道视频重建滤波器及缓冲器，用于复合视频及Y/C输出

MAX7443/MAX7444是适用于S视频和CVBS视频信号的低成本、三通道视频重建滤波器。该器件是抗混叠和DAC平滑滤波视频应用的理想选择，如机顶盒、DVD播放器、硬盘摄录机(HDR)，以及个人视频摄录机等。这些滤波器采用+5V单电源供电，它们为NTSC、PAL以及标清数字电视(SDTV)视频系统而优化。\n 每个通道都包括一个低通滤波器和一个可以驱动两个标准150Ω视频负载的可调增益输出缓冲器。该输出缓冲器既可以驱动AC负载，也可以驱动DC负载，消隐电平经过反向匹配电阻之后低于1V。Y和C视频输入相加后产生复合视频输出。MAX7444提供高频提升以改善图像的清晰度。MAX7443具有极为 \n• 适用于CVBS和Y/C (S视频)的三通道滤波器和缓冲器 \n• 滤波器响应特别适合于NTSC、PAL和隔行SDTV信号 \n• 27MHz下阻带抑制为41dB (典型值) \n• 通带响应-0.3dB (典型值) \n• 低消隐电平电压允许直流耦合输出 \n• 每通道可驱动两个150Ω视频负载 \n• +5V单电源供电 \n• 细小的8引脚薄型QFN或8引脚SO封装;

TTL HD74/HD74S Series

VOLTAGE DETECTOR

VOLTAGE DETECTOR This IC series is usable for the CPU system of all types and wired logic system as it has the function of detecting the power supply voltage at the time of initial resetting after switching the power supply on and after instantaneous break in power supply voltage there-by accur

TONE CONTROL AND SURROUND DIGITALLY CONTROLLED AUDIO PROCESSOR WITH AGC

DESCRIPTION The TDA7443D is a volume tone (bass and treble) balance (Left/Right) processor for quality audio applications in Hi-Fi systems. Selectable input gain is provided. Control of all the functions is accomplished by serial bus. The AC signal setting is obtained by resistor networks and s
