ADI ADN4693E-1 多点低压差分信号(M-LVDS)收发器解决方案
ADI公司的ADN4693E-1是多点低压差分信号(M-LVDS)收发器(驱动器和接收器对), 工作速率最高可达200 Mbps (100 MHz)不归零(NRZ). 接收器可在该器件的共模电压范围内利用低至±50 mV的差分输入检测总线状态. 从总线引脚上实现高达±15 kV的静电放电(ESD)保护. ADN4693E-1遵循M-LVDS的TIA/EIA-899标准设计,为TIA/EIA-644 LVDS器件添加了额外的多点能力.ADN4693E-1采用具有25 mV迟滞的1类接收器,因此缓慢变化的信号或输入损耗不至于引起输出振荡.全双工器件采用紧凑的4 mm x 4mm LFCSP封装. ADN4693E-1的额定温度范围为-40⁰C至+120⁰C结温范围. 空气放电：≥±15 kV HBM,接触放电：≥±8 kV HBM,空气放电：≥±10 kV IEC 61000-4-2,接触放电：≥±8 kV IEC 61000-4-2

The ADN4693E-1 is a multipoint, low voltage differential signaling (M-LVDS) transceiver (driver and receiver pair) that can operate at up to 200 Mbps (100 MHz) nonreturn to zero (NRZ). The receiver detects the bus state with a differential input of as little as ±50 mV
over the common-mode voltage range of the device. Electrostatic discharge (ESD) protection of up to ±15 kV is implemented on the bus pins. The ADN4693E-1 is designed to the TIA/EIA-899 standard for use in M-LVDS networks and complements TIA/EIA-644
