Analog Devices / Maxim Integrated MAX9240A 25 位 GMSL 解串器

Maxim MAX9240A 25 位紧凑型解串器被设计用于通过 50Ω同轴电缆或 100Ω 屏蔽双绞线（STP）电缆与 GMSL 串行器对接。该 Maxim 器件与 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。双输出可选通发送出每个像素时钟周期上一半的并行字。双输出可与具有双输入功能的 GMSL 串行器一起搭配使用。MAX9240A 有一个内置控制通道，可在 9.6kbps 至 1Mbps 条件下操作。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。为了与长电缆一起使用，器件配备了可编程均衡器。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。器件工作温度范围为 -40°C 至 +105°C 的。

MAX9240A features an embedded control channel that operates at 9.6kbps to 1Mbps. Using the control channel, a microcontroller can program the serializer/deserializer and peripheral device registers at any time, independent of video timing. Two programmable GPIO ports and a continuously sampled GPI input are available. 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. The device operates over a -40°C to +105°C temperature range.
