CXAS42209交叉点交换机为应用程序提供了灵活的选项。16个输入可以路由到4个输出中的任何一个。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。对于一对多路由，多个输出可以连接到同一个输入通道。输入输出路由通过与I2C兼容的数字接口控制。
对于模拟信号切换应用，根据配置，4个输出可以是4个单输出或2个差分输出。交叉点结构可以降低PCB的复杂度。对于数字信号切换，CXAS42209支持高达400kHz的数字信号。
CXAS42209的电阻曲线在整个模拟输入范围内非常平坦，确保切换音频信号时具有良好的线性度和低失真。对于视频应用程序，CXAS42209最多支持1080p或VGA视频。
CXAS42209有绿色TSSOP-28和TQFN-4×4-28L两种包装。它在-40℃到+85℃的环境温度范围内工作。

产品概述 返回TOP
The CXAS42209 crosspoint switch provides flexible options for applications. The 16 inputs can be routed to any of 4 outputs. Each input can be routed to one or more outputs, but only one input can be routed to any one output. More than one output can connect to the same input channel for one-to-many routing. The input to output routing is controlled via an I2C-compatible digital interface.
For analog signal switching application, 4 outputs can be 4 single outputs or 2 differential outputs depending on configuration. Crosspoint structure can reduce PCB complexity. For digital signal switching, CXAS42209 supports up to 400kHz digital signal.
The resistance profile of CXAS42209 is very flat over the full analog input range, ensuring excellent linearity and low distortion when switching audio signals. For video application, CXAS42209 supports up to 1080p or VGA video.
The CXAS42209 is available in Green TSSOP-28 and TQFN-4×4-28L packages. It operates over an ambient temperature range of -40℃ to +85℃.
