Product Details

The AD-FMCADC7-EBZ is a single channel high speed data acquisition board featuring the AD9625 12bit, ADC sampling at 2500 MSPS and a ADL5567 low distortion, 4.8 GHz, differential amplifier driving the converter. The FMC form factor supports the JESD204B high speed serial interface. All clocking is supported using the on-board ADF4355-2 wideband PLL with VCO. This product is designed for sampling wide bandwidth analog signals from DC to 1.8GHz. The combination of wide input bandwidth, high sampling rate, and excellent linearity of the AD9625 is ideally suited for spectrum analyzers, data acquisition systems, and a wide assortment of military electronics applications.

The 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’s 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 allow for true DC coupling on the analog input of the amplifier throughout the signal chain to the converter. Yielding the widest spectrum possible for the AD-FMCADC7-EBZ.

The reference design includes the device data capture via the JESD204B serial interface and the SPI interface. The samples are written to the external DDR-DRAM. It allows programming the device and monitoring it’s internal registers via SPI.
