Texas Instruments ISO782xLL双通道隔离式LVDS缓冲器
Texas Instruments ISO782xLL双通道隔离式LVDS缓冲器是高性能、隔离式双LVDS缓冲器，具有8000VPK隔离电压。该器件具有很强的抗电磁干扰性，辐射低、功耗低，此外还能隔离LVDS总线信号。每个隔离通道都有一个由二氧化硅 (SiO2) 绝缘隔栅分开的 LVDS 接收和发射缓冲器。ISO7820LL 器件具有两个正向通道。ISO7821LLS 器件具有一个正向通道和一个反向通道。凭借创新的芯片设计和布局技术，ISO782xLL的电磁兼容性得到了显著增强，从而可确保提供系统级 ESD、EFT和浪涌保护并符合辐射标准。

ISO782xLLxEVM Isolated Dual LVDS Unidirectional Buffer EVMs
Texas Instruments ISO782xLLxEVM Isolated Dual LVDS Unidirectional Buffer Evaluation Modules (EVMs) feature the ISO782xLLx Isolated Dual LVDS Buffers. The ISO782xLLx has 100Ω differential termination at the input and output. It can also support accurate measurement of eye diagram and common mode termination at the output. These evaluation modules have a provision for measuring timing parameters accurately and for output common-mode termination. Each module is tested for the device's functionality and allows the designer to evaluate the user's design with each device.
