Tools & Simulations

ADIsimDDS (Direct Digital Synthesis)

ADIsimDDS uses mathematical equations to model and illustrate the overall performance of the selected device. ADIsimDDS calculates the required FTW, given the reference clock frequency and desired output frequency. This tool also models an estimate of the overall spectral performance, and allows the user to explore the effects of external reconstruction filters.

Product Details

The ADMX2001 is a measurement module that simplifies the development of impedance measurement systems or can be used to enhance the capabilities of existing test platforms. Using high-performance mixed-signal and processing algorithms, the ADMX2001 can measure changes in capacitance as small as 0.1fF and resistance values up to 20MΩ, often required to test semiconductor devices, electronic components, and sensors. Moreover, built-in measurement algorithms enable the ADMX2001 to deliver fully calibrated complex impedance or admittance measurement results in various formats, including parallel and series combinations of resistance, capacitance, and inductance.

Applications

  • Automated test equipment
  • Semiconductor characterization
  • Wafer acceptance test
  • Electrical Impedance Spectroscopy

Features and Benefits

  • Full featured evaluation board (EVAL-CN0304-SDZ) for the AD9834
  • Graphic user interface software for board control and data analysis
  • Connector to the EVAL-SDP-CB1Z System Demonstration Platform (SDP) board
  • Various power supply and reference link options

Product Details

The AD9834 is a 75 MHz, low power DDS device capable of producing high performance sine and triangular outputs. It also has an on-board comparator that allows a square wave to be produced for clock generation. Consuming only 20 mW of power at 3 V makes the AD9834 an ideal candidate for power-sensitive applications.

The EVAL-CN0304-SDZ board is used in conjunction with a EVALSDP- CB1Z board available from Analog Devices, Inc. The USB to SPI communication to the AD9834 is completed using this Blackfin®-based development board.

A high performance, on-board 75 MHz trimmed general oscillator is available to use as the master clock for the AD9834 system. Various links and SMB connectors are also available on the EVALCN0304- SDZ board to maximize the usability.

Complete specifications for the AD9834 are provided in the AD9834 data sheet, available from Analog Devices. Consult the AD9834 data sheet in conjunction with this user guide when using the evaluation board.
