Product Details

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.

Product Details

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
