串行总线缓冲器、扩展器和加速度计

ADI公司的I2C解决方案系列支持热插拔、双线式双向总线缓冲器,可将I/O卡插入带电背板中,而不会损坏数据和时钟总线。其他支持的双线式总线包括SMBus、PMBus、ATCA智能平台管理总线(IPMB)和HDMI DDC总线。I2C/SMBus加速度计可改善总线转换特性,支持多个器件连接或更长、更多容性互连,而不影响压摆率或总线性能。ADI的软件可编程和引脚可选I2C多路复用器有助于解决I2C地址限制,增加扇入或扇出能力,并为一体化解决方案集成总线缓冲器和上升时间加速度计。电阻可配置I2C地址转换器可配置超过100个独特的从机地址,使多个具有相同地址的从器件可在同一总线上共存。
