HIGH SPEED ADC EVALUATION BOARD SOFTWARE AND BEHAVIORAL MODELS

For simple product selection, a simple web based application is accessible from the product pages of devices that are supported by ADIsimADC. This tool requires no downloads and allows control of the test conditions and 'design' specific performance plots. Results are graphed which greatly reduces the uncertainty of how a part will perform in an application. The tool also allows input of desired operating conditions and required performance levels and it will recommend suitable devices to the user.

• Advanced online product selection tool;
• Vary input amplitude and frequency;
• Single tone or two-tone FFT analysis;
• Amplitude and frequency sweeps;
• Generate a list of ADCs that meet your signal processing requirements.

For designers who are selecting or evaluating high speed ADCs, VisualAnalog™ is a software package that combines a powerful set of simulation and data analysis tools with a user-friendly graphical interface. Many designers are familiar with ADCAnalyzer - a tool that models ADC performance with varying input frequencies and sample rates. VisualAnalog takes this concept further by allowing designers to customize their input signal and data analysis. An input signal can be constructed from sine waves, noise sources, and vector data to see how an ADC will perform in real world conditions. The data analysis functions are expanded from the basic FFTs that are available in ADCAnalyzer as well. Customizable calculations allow designers to predict adjacent channel power ratio (ACPR) and display I/Q constellation plots on simulated ADC outputs or data collected from evaluation boards. VisualAnalog™ is also used as a controller for a new data capture board (HSC-ADC-EVALCZ).

• Configure ADC evaluation boards with HSC-ADC-EVALC or HSC-ADC-EVALB data capture kit
• Analyze data from HSC-ADC-EVALC
• Model ADC performance with complex input waveforms
• Plot I & Q constellations
• Create customized power calculations
