2A, 1.2MHz Synchronous Step-Down DC-to-DC Regulator
The ADP2119/ADP2120 can support input voltages from 2.3V to 5.5V. The output voltage can be adjusted from 0.6V to input voltage (VIN) for the adjustable version, while the fixed output version is available in preset output voltage options of 3.3V, 2.5V, 1.8V, 1.5V ,1.2V and 1.0V. The ADP2119/ADP2120 require minimal external parts and provide a high efficiency solution with their integrated power switches, synchronous rectifier, and internal compensation. Each IC draws less than 3 μA current from the input source when it is disabled. Other key features include under voltage lockout(UVLO), integrated soft start to limit inrush current at startup, overvoltage protection (OVP), over current protection (OCP) and thermal shutdown (TSD).Applications

The AD-FMCADC2-EBZ is a high-speed data acquisition board featuring the AD9625 single channel ADC at 2500 MSPS, in a FMC form factor which supports the JESD204B high speed serial interface. The AD9625 is a 12-bit monolithic sampling analog-to-digital converter (ADC) that operates at conversion rates of up to 2.5 GSPS. This product is designed for sampling wide bandwidth analog signals up to the second Nyquist zone. 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, such as radar and jamming/anti-jamming measures.
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 synchronizing multiple AD-FMCADC2-EBZ boards together. For more information on synchronization please refer to A Test Method for Synchronizing Multiple GSPS Converters.
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 its internal registers via SPI.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
