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是一款多点低压差分信号(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. 全双工器件采用紧凑的16引脚4 mm x 4mm LFCSP封装. 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. 总线引脚提供增强型ESD保护: 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.器件的额定温度范围为-40⁰C至+120⁰C结温范围.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链路以及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, 典型全双工M-LVDS控制器/器件网络以及评估板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

LVDS devices with additional multipoint capabilities.

The ADN4693E-1 features a Type 1 receiver with 25 mV of hysteresis so that slow-changing signals or loss of input does not lead to output oscillations.

This full-duplex device is available in a compact 16-lead, 4 mm × 4 mm lead frame chip scale package (LFCSP). The ADN4693E-1 is specified over the −40°C to +120°C junction temperature range.
