The reference design includes the device data capture via the JESD204B serial interface and the SPI interface. Yielding the widest spectrum possible for the AD-FMCADC7-EBZ. 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. 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. This board is targeted to use the ADI reference designs that work with Xilinx development systems. 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). Although this board does meet most of the FMC specifications, it’s not meant as a commercial off the shelf (COTS) board. The board meets most of the FMC specifications in terms of mechanical size, mounting hole locations, and more.
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. This product is designed for sampling wide bandwidth analog signals from DC to 1.8GHz. All clocking is supported using the on-board ADF4355-2 wideband PLL with VCO. The FMC form factor supports the JESD204B high speed serial interface. 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 ADP1754/ADP1755 are available in a 16-lead, 4 mm × 4 mm LFCSP, making them not only very compact solutions, but also providing excellent thermal performance for applications requiring up to 1.2A of output current in a small, low profile footprint. A power good output allows power system monitors to digitally check the health of the output power rail voltage. The ADP1754/ADP1755 allows an external soft start capacitor to be connected to program the start-up. The ADP1755 is available in an adjustable version, which allows output voltages that range from 0.75 V to 3.3 V via an external divider. The ADP1754 is available in seven fixed output voltage options. Using an advanced proprietary architecture, they provide high power supply rejection, low noise, and achieve excellent line and load transient response with a small 4.7 ♟ ceramic output capacitor. These Low V in / V out LDOs are ideal for regulation of nanometer FPGA geometries operating from 2.5V down to 1.8V I/O rails, and powering core voltages down to 0.75V. The ADP1754/ADP1755 are CMOS, low dropout linear regulators that operate from 1.6 V to 3.6 V and provide up to 1.2A of output current.
