FMCADCX001: Dual AD9250 FMC ADC Expansion Module

0 views June 12, 2019 kavya-konda 0

Introduction

The Numato Lab FMCADCX001 ADC Expansion Module features two Analog Devices AD9250 ICs with each IC being a dual, 14-bit ADC with a sampling rate of up to 250 MSPS, thus providing a total of 4 analog input channels. The AD9250 is designed to support communications applications where low cost, small size, wide bandwidth, and versatility are desired. This module is designed to be used with Numato Lab’s FPGA boards featuring FMC connectors, and can additionally be used with any FPGA board supporting the ANSI/VITA 57.1 FMC connector.

 

Applications

  • Digital Instrumentation
  • Product prototyping
  • Low-Cost Digital Oscilloscopes
  • Data acquisition
  • Electronic test and measurement equipment

Board Features

  • ANSI/VITA 57.1 compliant FMC connector for mating with compatible FPGA carrier cards
  • 4 Analog Inputs: 1.4 Vp-p to 2.0 Vp-p (1.75 Vp-p nominal)
  • AD9250 SNR = 70.6 dBFS @ 185 MHz AIN and 250 MSPS
  • 14-bit resolution, 250 MSPS maximum sampling rate
  • Energy saving power-down modes
  • Total power consumption per AD9250: 711 mW at 250 MSPS
  • AD7291: 12-bit SAR ADC with an internal temperature sensor for power rails’ voltage monitoring
  • Dimension: 84.01mm x 69.00mm
