Analog Devices / Maxim Integrated MAX9272A 28位GMSL解串器

Maxim MAX9272A 28位紧凑型解串器设计用于通过50Ω同轴电缆或100Ω屏蔽双绞线(STP)电缆与GMSL串行器对接。Maxim器件适用于汽车摄像机系统应用，与MAX9271或MAX9273串行器配对使用。并行输出可编程为单输出或双输出。Maxim MAX9272A GMSL解串器有一个内置控制通道，可工作于9.6kbps或1Mbps。利用控制通道，微控制器能够随时设置串行器、解串器和任何外设寄存器，而不受制于视频时钟。有两个可编程GPIO端口和一个连续采样GPI输入可用。器件配备了可编程均衡器，便于搭配长电缆使用。并行输出上有可编程扩频。串行输入满足ISO 10605和IEC 61000-4-2 ESD标准。核心电源供电范围为1.7V至1.9V，I/O电源范围为1.7V至3.6V。

For use with longer cables, the device has a programmable equalizer. Programmable spread spectrum is available on the parallel output. The serial input meets ISO 10605 and IEC 61000-4-2 ESD standards. The core supply range is 1.7V to 1.9V and the I/O supply range is 1.7V to 3.6V.
