AD-FMCADC3-EBZ

12-Bit, 2500 MSPS, JESD204B, RF Data Acquisition FMC Board.

Warning

The AD-FMCADC3-EBZ is a legacy product and is no longer actively supported. This documentation is provided for reference only.

Overview

The AD-FMCADC3-EBZ is a high speed data acquisition board featuring the AD9625 single channel ADC at 2500 MSPS and the ADA4961 Low Distortion, 3.2 GHz, RF Digital Gain Amplifier (DGA) driving the converter. The FMC form factor supports the JESD204B high speed serial interface. This board meets most of the FMC specifications in terms of mechanical size, mounting hole locations, and more.

Although this board does meet most of the FMC specifications, it is not meant as a commercial off the shelf (COTS) board. If you want a commercial, ready to integrate product, please refer to one of the many FMC manufacturers and the FMC specification (ANSI/VITA 57.1). This board is targeted to use the ADI reference designs that work with Xilinx development systems. ADI provides complete source (HDL and software) to re-create those projects (minus the IP provided by the FPGA vendors, which we use), but may not provide enough info to port this to your custom platform.

The design of the board is specifically tailored to synchronizing multiple AD-FMCADC3-EBZ boards together. For more information on synchronization, please refer to A Test Method for Synchronizing Multiple GSPS Converters.

The card contains:

• AD9625 12-bit ADC with sampling speeds of up to 2500 MSPS, with a JESD204B digital interface.

• ADA4961 Low Distortion, 3.2 GHz, RF Digital Gain Amplifier.

• ADP7104 20 V, 500 mA, low noise, CMOS LDO

• ADP1753 low dropout linear regulator (1.6 V to 3.6 V, up to 800 mA)

• ADP2119 2 A, 1.2 MHz, synchronous step-down DC-to-DC regulator

• ADP1741 2 A, low V_IN, low dropout, CMOS linear regulator

• ADR280 ultralow power, high PSRR voltage reference

Warning

All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection. Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.
