ADN4691E/ADN4693E/ADN4696E/ADN4697E都是多点低电压差分信号(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)。接收器可在-1 V至+3.4 V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。总线引脚上提供最高可达±15 kV的ESD保护。这些器件遵循M-LVDS的TIA/EIA-899标准，为TIA/EIA-644 LVDS器件添加了额外的多点能力。

ADN4691E/ADN4693E都是具有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。ADN4696E/ADN4697E都是具有失调阈值的2类接收器，可在总线处于空闲状态（总线空闲故障安全）或输入端断开（开路故障安全）时保证输出状态。

这些器件提供8引脚SOIC封装的半双工配置(ADN4691E/ADN4696E)或14引脚SOIC封装的全双工配置(ADN4693E/ADN4697E)。

AD-SYNCHRONA14-EBZ：Multichannel System Clocking Device

The AD-SYNCHRONA14-EBZ is an ideal self-contained device to use in evaluation and prototyping of applications that need a highly accurate frequency and phase-controlled source clock. It is designed around the Analog Devices AD9545 and HMC7044 and greatly simplifies clock distribution and multi-channel synchronization in complex systems. It is intended to be used by trained professionals in a laboratory environment, and not intended as an end product for commercial use. It can be taken as a complete reference design and customised as required for any end customer applications. Full design details are made available free of charge.

The AD-SYNCHRONA14-EBZ comes in a 1U mechanical form factor. Using popular industry connector SMA and TwinAX interfaces most labs will already have the needed cables.

With its internal OCXO it can operate in standalone mode or be fed from a choice of external sources, such as 3 separate high speed differential clock inputs, a 10MHz reference and 1PPS. This flexibility combined with the capability to select either of the internal VCXO options of 100MHz or 122.88MHz, gives almost unlimited choice for the frequency of interest and accuracy needed for a wide variety of application areas.

APPLICATIONS

High accuracy reference clock distribution Systems clocked from a single source Clocks derived from 100MHz or 122.88MHz Phased Array Systems, RADAR, EW, SATCOMS, SDR Bench Equipment Remote controlled operation
