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, 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.器件遵循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.器件采用具有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.器件采用紧凑的4 mm x 4mm 16引脚LFCSP封装.ADN4693E-1的额定温度范围为-40⁰C至+120⁰C结温范围.器件的共模范围为-1 V至+3.4 V,允许在2 V接地噪声下进行通信.总线引脚提供增强型ESD保护,包括空气放电：≥±15 kV HBM,接触放电：≥±8 kV HBM;空气放电：≥±10 kV IEC 61000-4-2和接触放电：≥±8 kV IEC 61000-4-2.主要用在背板和电缆多点数据传输,多点时钟分配,低功耗,高速替代器件,可缩短RS-485链路网络和无线基站基础设施,电网基础设施和继电器保护系统.本文介绍了ADN4693E-1主要特性,功能框图, 全双工M-LVDS控制器/器件网络接收器框图以及评估板EVAL-ADN4693E-1EBZ主要特性,电路图,材料清单和PCB设计图.
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
