Analog Devices Inc. Analog Devices ADV7281-MA 10 位 SD 视频解码器
Analog Devices ADV7281-MA 视频解码器是功能丰富的单芯片、多格式视频解码器，可自动检测标准模拟基带视频信号，兼容复合、S 视频和分量视频形式的 NTSC、PAL 和 SECAM 全球标准信号。ADV7281-MA 可将模拟视频信号转换为 YCrCb 4:2:2 视频数据流，它与 8 位 ITU-R BT.656 接口标准兼容。ADV7281-MA 可将模拟视频信号转换为 8 位、YCrCb 4:2:2 视频数据流，可通过移动工业处理器接口(MIPI)的 CSI-2 接口进行输出。该器件的模拟视频输入端支持单端、伪差分和全差分信号。ADV7281-MA 提供 8 路模拟输入和三路通用输出。该器件通过双线式串行双向端口（I2C 兼容型）进行编程，并且采用 1.8V CMOS 工艺制造。该器件提供 LFCSP 封装选件，非常适合空间受限的便携式应用。
ADV7281-MA converts the analog video signals into an 8-bit YCrCb 4:2:2 video data stream that is output over a mobile industry processor interface (MIPI) CSI-2 interface. The analog video inputs of the device accepts single-ended, pseudo differential, and fully differential signals.
The ADV7281-MA provides eight analog inputs and three general-purpose outputs. The device is programmed via a 2-wire, serial bidirectional port (I2C compatible) and are fabricated in a 1.8V CMOS process. The LFCSP package option makes these decoders ideal for space-constrained portable applications.
