数字视频编码器，内置Macrovision防复制电路

ADV7175A/ADV7176A均为集成式数字视频编码器，能够将数字CCIR-601 4:2:2 8位或16位分量视频数据转换为与全球标准兼容的标准模拟基带电视信号。4:2:2 YUV视频数据通过插值放大为像素速率的两倍。利用一个片内32位数字频率合成器（同样工作于两倍像素速率）产生的副载波频率对色差分量(UV)进行正交调制。两倍像素速率采样模式可以实现更佳的信噪比。内置10位查找表的32位DDS产生的副载波在频率和相位两个方面均非常出色。除复合输出信号外，还可输出S视频(Y/C)视频、YUV或RGB视频信号。Y/C、YUV或RGB格式可以与复合视频信号一起在模拟输出端同时提供。 • ITU-R BT601/656 YcrCb至PAL/NTSC视频编码器\n\n• 高质量、10位视频DAC\n\n• 积分非线性：\n• 适合彩色副载波的32位直接数字频率合成器\n\n• 支持多标准视频输出：复合(CVBS)分量S视频(Y/C)分量YUV和RGB\n\n• EuroSCART输出(RGB + CVBS/LUMA)支持视频输入数据端口：CCIR-656 4:2:2 8位并行输入格式4:2:2 16位并行输入格式\n\n• 全视频输出驱动或低信号驱动功能34.7 mA（最大值，37.5 Ω）（双端接75R）5 mA（最小值，外部缓冲）\n\n• 可编程同步复合和S视频Y/C或;
