AD8197BASTZ-RL屬于集成電路（IC）的視頻處理。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD8197BASTZ-RL視頻處理一種集成電路 (IC) 半導(dǎo)體器件，設(shè)計(jì)用于在放大、增強(qiáng)、編碼器和解碼器（編解碼器）、緩沖、校準(zhǔn)、處理、信號(hào)調(diào)節(jié)、調(diào)制與解調(diào)、轉(zhuǎn)換、傳輸、伽瑪校正、切換、OSD、數(shù)字化和多路復(fù)用等應(yīng)用中處理音頻和/或視頻信號(hào)。

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.
