ADP198是一款高端负载开关，采用1.65 V至6.5 V电源供电，可防止电流反向从输出端流向输入端。负载开关可提供电源域隔离，有助于保持子系统隔离和独立供电，从而降低功耗。ADP198内置一个低导通电阻P沟道MOSFET，支持1 A以上的连续负载电流。ADP198具有2.5 μA的低静态电流和超低关断电流，因此非常适合电池供电的便携式设备使用。借助内置的使能逻辑电平转换器，ADP198可兼容现代处理器和GPIO控制器。LFCSP封装还允许用户对启动时间进行编程，以控制上电时的浪涌电流。

ADP198采用4引脚、1 mm x 1 mm、0.5 mm间距、超小型WLCSP封装。此外还提供8引脚2 mm x 2 mm x 0.55 mm、0.5 mm间距LFCSP封装。

EVAL-ADP198：ADP198 Evaluation Board

The ADP198 evaluation boards are used to demonstrate the functionality of the ADP198 power switch.

Simple device measurements such as VIN to VOUT resistance (RDSON), ground current, and off state current can be demonstrated with just a single voltage source, a voltmeter, an ammeter, and load resistors.

Full details about the ADP198 power switch are available in the ADP198 data sheet, which should be consulted when using the ADP198 evaluation boards.

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
