概览
The GS12182 is a low-power, multi-rate, re-timing cable driver supporting rates up to 12G UHD-SDI, inclusive of 10GbE. It is designed to receive 100Ω differential input signals, automatically recover the embedded clock from the digital video signal and re-time the incoming data, and transmit the re-timed signal over 75Ω coaxial cables. Each of the 100Ω trace inputs support up to 17dB of insertion loss.
集成的眼图监控器可提供对后均衡输入信号的无干扰任务模式分析。 256x128 分辨率扫描矩阵可提供准确的信号分析，加速原型生成，实现场分析。 内置宏可实现定制截面分析以及快速横向和纵向眼张开度测量。
扫描和可配置空间及时间阈值之间高相位一致时，可在场中部署算法，用于分析长期信号质量变化（浴盘图），从而缩短系统安装设施间歇误差的故障排除时间。 两个电缆驱动器具有可高度配置的预加重和摆幅控制，用于补偿远距离跟踪和控制器丢失。 此外，还为每个电缆驱动器输出提供自动和用户可选的输出压摆率控制。
GS12182 与 GS12181 和 GS12281 单输入 12G UHD-SDI 多速率重定时电缆驱动器、GS12081 12G UHD-SDI 多速率电缆驱动器，以及 GS3281 3G SDI 多速率重定时电缆驱动器具有引脚兼容性。

The Challenge of Drain Grate Maintenance
In urban and industrial water management, drain grates play a crucial role in preventing debris from clogging sewage systems, retention basins and hydropower plants. These grates filter out foliage, branches and other obstructions, ensuring the smooth flow of water. However, over time, debris accumulation can lead to blockages, increasing the risk of flooding and requiring frequent manual inspections.
