Analog Devices Inc. ADV7283 SDTV 视频解码器
亚德诺半导体 ADV7283 SDTV 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。ADV7283 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。ADV7283 的 6 个模拟视频输入端支持单端、伪差分和全差分信号。去隔行器（I2P转换器），具有逐行格式视频输出能力。ADV7283 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。ADV7283 在设计上采用节约空间的 LFCSP 表面贴装式、符合 RoHS 指令的封装，具有汽车级 −40°C 到 +105°C 温度范围，以及 −40°C 到 +85°C 温度范围，使器件适合用于汽车以及工业应用。
ADV7283's six analog video inputs accept single-ended, pseudo-differential, and fully differential signals. The deinterlacer (I2P converter) enables the device to output video in a progressive format. Fabricated in a 1.8V CMOS process, the ADV7283 is programmed via a 2-wire, serial bidirectional port (I²C compatible). Designed in a space-saving LFCSP surface-mount, RoHS-compliant package, the ADV7283 is available in an automotive-grade rated over the -40°C to 105°C temperature range, as well as a −40°C to 85°C temperature range, making the device ideal for both automotive and industrial applications.
