CXAS42205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I2C兼容数字接口标准模式8×6交叉点开关矩阵一对一或一对多输入输出切换提供八个输入路由到六个输出中的任何一个

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。

The CXAS42205 provides eight inputs that can be routed to any of six outputs. Each input can be routed to one or more outputs, but only one input may be routed to any output.

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℃.
