Kit Overview

The AD9250-250EBZAD9250-250EBZ is the AD9250AD9250 evaluation board that can be used to evaluate Analog Devices Inc high speed AD9250-250AD9250-250 ADC.The AD9250-250EBZAD9250-250EBZ board and companion HSC-ADC-EVALDZHSC-ADC-EVALDZ high-speed data capture card comprise a signal performance-optimized complete evaluation system for the AD9250-250AD9250-250. The captured data can be analyzed using a laptop computer and ADI’s free VisualAnalog™ software.

The AD9250AD9250 is a dual, 14-bit ADC with sampling speeds of up to 250 MSPS. The AD9250AD9250 is designed to support communications applications where low cost, small size, wide bandwidth, and versatility are desired.

The ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. The ADC cores feature wide bandwidth inputs supporting a variety of user selectable input ranges. An integrated voltage reference eases design considerations. A duty cycle stabilizer is provided to compensate for variations in the ADC clock duty cycle, allowing the converters to maintain excellent performance. The JESD204B high speed serial interface reduces board routing requirements and lowers pin count requirements for the receiving device.

Flexible power-down options allow significant power savings, when desired. Programmable overrange level detection is supported for each channel via the dedicated fast detect pins. Programming for setup and control are accomplished using a 3-wire SPI-compatible serial interface.

Key Applications: Diversity radio systems, Multimode digital receivers (3G) TD-SCDMA, WiMax, WCDMA, CDMA2000, GSM, EDGE, LTE, DOCSIS 3.0 CMTS upstream receive paths, HFC digital reverse path receivers, I/Q demodulation systems, Smart antenna systems, Electronic test and measurement equipment, RADAR receivers, COMSEC radio architectures, IED detection/jamming systems, General-purpose software radios, Broadband data applications.

Software Tools

VisualAnalog™ Converter Evaluation Tool

VisualAnalog is a new way to test and characterize data converters, ADCs, and DACs alike. It provides the ability to customize the tests in a nearly limitless manner using a simple graphical user interface. VisualAnalog interfaces seamlessly with the DAC pattern generator (DPG) for DAC evaluation and the following ADC data capture boards for ADC evaluation:

HSC-ADC-EVALA
HSC-ADC-EVALB
HSC-ADC-EVALCHSC-ADC-EVALC
HSC-ADC-EVALDZHSC-ADC-EVALDZ

SPIController - High Speed ADC SPI Control Software

The high speed ADC SPI program allows the user to control advanced features on high speed, analog-to-digital converters (ADC) with SPI capability. This advanced controller program is used in conjunction with the high speed data capture boards and and specific device evaluation boards to manipulate and control SPI-accessible features. The SPI Controller program can run as a standalone application on a Windows platform, or in conjunction with any available data analysis tool, such as VisualAnalog™ or ADC Analyzer™.

The software includes advanced features to ensure a smooth transition from evaluation into prototyping and production. When a desired configuration is attained, the program includes a C-code generator that provides compatible C source code that can be incorporated into customer-developed software. For users without an available microcontroller, the software also includes an assembly code generator that produces code targeted for the ultralow cost PIC12F629 microcontroller.
