CXAS42204交换机矩阵为当今的视频应用程序提供了灵活的选项。可路由到9个输出中任意一个的12个输入。每个输入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一个输出。输入输出路由通过I2C兼容的数字接口控制。
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，在~1.3V的电压下，输入可以在内部偏置到没有同步（色度、Pb、Pr）的中心信号。这些直流输出电平用于6dB增益设置。更高的增益设置相应地增加直流输出电平。输入钳位/偏置模式通过I2C选择。未使用的输出可能会断电以减少功耗。

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 signals without sync (Chroma, Pb, Pr) at ~1.3V. These DC output levels are for the 6dB gain setting. Higher gain settings increase the DC output levels accordingly. The input clamp/bias mode is selected via I2C. Unused outputs may be powered down to reduce power dissipation.
The CXAS42204 is available in Green SSOP-28 and TSSOP-28 packages. It operates over an ambient temperature range of -40℃ to +85℃.
