FPGA mezzanine card

20 March 2013 Computer/Embedded Technology

Analog Devices introduced an FPGA mezzanine card (FMC) that incorporates JEDEC JESD204B SerDes (serialiser/de-serialiser) technology to allow digital and analog designers to simplify high-speed data converter-to-FPGA connectivity.

The FMC176 is a 14-bit, 250 MSps A/D converter FMC that supports JESD204B Subclass 1 deterministic latency, providing the connectivity and functionality to quickly combine with Xilinx’s Kintex-7 and Virtex-7 FPGA platforms in a variety of compute-intensive FPGA-based applications. It also features two Analog Devices AD9129 14-bit RF D/A converters to support high-speed communications applications with up to 5,6 GSps throughput.

The card features two AD9250, dual-channel, 14-bit, 250 MSps A/D converters with JESD204B-compatible serial output data interface and two AD9129s.

The 250 MSps 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 onboard AD9250s supports Subclass 1 deterministic latency and a SYNCREF signal for precise synchronisation of all four channels.

The FMC176 is mechanically and electrically compliant with FMC standard ANSI/VITA 57.1. They have a high-pin-count connector, front panel I/O and can be used in a conduction-cooled environment.

The card allows flexible control on sampling frequency, analog input gain and over-range detection through serial communication buses. It is equipped with power supply and temperature monitoring and offers several power-down modes to switch off unused functions or protect the card from overheating.
