CXAS42216交叉点交换机为信号交换应用提供了灵活的选项。16个输入可以路由到8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。输入输出路由通过串行接口控制。许多CXAS42216设备可以独立使用，也可以构造成菊花链控制的串行接口。
对于模拟信号切换应用，根据配置，8个输出可以是8个单输出或4个差分输出。交叉点结构可以降低PCB的复杂度。
CXAS42216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，CXAS42216最多支持1080p或VGA视频。

The CXAS42216 crosspoint switch provides flexible options for signal switching applications. The 16 inputs can be routed to any of 8 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 a serial interface. Many CXAS42216 devices can be used independently or constructed as daisy-chain controlled serial interface.

For analog signal switching application, 8 outputs can be 8 single outputs or 4 differential outputs depending on configuration. Crosspoint structure can reduce PCB complexity.

The resistance profile of CXAS42216 is very flat over the full analog input range, ensuring excellent linearity and low distortion when switching audio signals. For video application, CXAS42216 supports up to 1080p or VGA video.

The CXAS42216 is available in Green LQFP-7×7-32L package. It operates over an ambient temperature range of -40℃ to +85℃.
