Electronica: ADI designs high speed FPGA interface board

The FPGA mezzanine card (FMC) is a 14-bit, 250Msample/s analogue-to-digital converter board designed to interface with Xilinx’s Kintex-7 and Virtex-7 FPGAs in various applications with JESD204B subclass-1 deterministic latency.

“This is a viable system for customers to prototype their design,” said Emre Onder, v-p marketing at Analog Devices.

“These board-level development platforms deliver out-of-the-box, direct connectivity between Xilinx FPGAs and ADI’s high-speed converters,” said Raj Seelam, director of marketing at Xilinx.

The FMC176  FPGA mezzanine card incorporates two AD9250, dual-channel, 14-bit, 250Msample/s ADCs with JESD204B-compatible serial output data interface and two AD9129 dual 16-bit 5.6Gsample/s RF digital-to-analogue converters.

The data channels can be clocked by an internal clock source or an externally supplied sample clock. There is one trigger input for customised sampling control.

Each of the two on-board AD9250 ADCs supports subclass-1 deterministic latency and a SYNCREF signal for synchronisation of all four channels.

The FMCs are mechanically and electrically compliant with FMC standard ANSI/VITA 57.1. The FMCs have a high-pin-count connector, front panel I/O and can be used in a conduction-cooled environment.

The board’s power supply has temperature monitoring and various power-down modes to switch off unused functions or protect the card from overheating.
