AD-FMCADC4-EBZ

14-Bit, 1000 MSPS, Quad-Channel, JESD204B, RF Data Acquisition FMC Board.

Warning

The AD-FMCADC4-EBZ is a legacy product that has been retired and is no longer available for sale. It has been removed from the HDL and software repositories, but is still available in the git history. This documentation is provided for reference only.

Overview

The AD-FMCADC4-EBZ is a high speed four-channel data acquisition board featuring two AD9680 dual channel ADCs at 1000 MSPS and four ADA4961 low distortion, 3.2 GHz, RF Digital Gain Amplifiers driving each converter. The FMC form factor supports the JESD204B high speed serial interface. All clocking and channel synchronization is provisioned on-board using the AD9528 clock generator.

Although this board does meet most of the FMC specifications, it is not meant as a commercial off the shelf (COTS) board. This board is targeted to use the ADI reference designs that work with Xilinx development systems.

The card contains:

  • AD9680 14-bit dual channel ADC with sampling speeds of up to 1250 MSPS, with a JESD204B digital interface.

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

  • AD9528 JESD204B Clock Generator with 14 LVDS Outputs

  • ADP2384 20 V, 4 A, Synchronous, Step-Down DC-to-DC Regulator

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

  • ADM7154 600 mA, Ultra Low Noise, High PSRR, RF Linear Regulator

  • ADM7172 6.5 V, 2 A, Ultralow Noise, High PSRR, Fast Transient Response CMOS LDO

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

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.
