AD8197BASTZ集成电路（IC）的视频处理规格书PDF中文资料

AD8197BASTZ属于集成电路（IC）的视频处理。由亚德诺半导体技术有限公司制造生产的AD8197BASTZ视频处理一种集成电路 (IC) 半导体器件，设计用于在放大、增强、编码器和解码器（编解码器）、缓冲、校准、处理、信号调节、调制与解调、转换、传输、伽玛校正、切换、OSD、数字化和多路复用等应用中处理音频和/或视频信号。

GENERAL DESCRIPTION

The AD8197B is an HDMI™/DVI switch featuring equalized TMDS® inputs and pre-emphasized TMDS outputs, ideal for systems with long cable runs. The AD8197B offers individual control of the on/off state of the TMDS input termination resistors via I2C® control. Outputs can be set to a high impedance state to reduce the power dissipation and/or to allow the construction of larger arrays using the wire-OR technique. The AD8197B is provided in a 100-lead LQFP, Pb-free, surface

mount package, specified to operate over the −40°C to +85°Ctemperature range.
