CXAS42205提供八个输入，可以路由到六个输出中的任何一个。每个输入都可以路由到一个或多个输出，但只有一个输入可以路由到任何输出。每个输入都支持一个集成的钳位选项，用于将同步视频的输出同步尖端电平设置为~600mV。或者，输入可以在~1.3V处内部偏置到没有同步（色度、Pb、Pr）的中心输出信号。所有输出均设计为驱动150Ω直流耦合负载。每个输出可编程为提供0dB或6dB的信号增益。输入输出路由和输入偏置模式功能通过I2C兼容数字接口控制。
•8×6交叉点开关矩阵
•一对一或一对多输入输出切换
•I2C兼容数字接口，标准模式
•支持SD、PS和HD视频
•输入钳位和偏置电路
•双端接75Ω电缆驱动器
•可编程0dB或6dB增益
•交流或直流耦合输入
•交流或直流耦合输出

产品概述 返回TOP
Each input supports an integrated clamp option to set the output sync tip level of video with sync to ~600mV. Alternatively, the input may be internally biased to center output signals without sync (Chroma, Pb, Pr) at ~1.3V.
All outputs are designed to drive a 150Ω DC-coupled load. Each output can be programmed to provide either 0dB or 6dB of signal gain.
Input-to-output routing and input bias mode functions are controlled via an I2C-compatible digital interface.
The CXAS42205 is available in Green TSSOP-24 package. It operates over an ambient temperature range of -40℃ to +85℃.
