FMC121 FPGA Mezzanine Card

Analog input and output


We recommend the following alternative solutions:


The FMC121 provides two 16-bit A/D channels up to 1 GSPS and two 16-bit D/A channels up to 1.4 GSPS data rate with a 2.8 GSPS update rate.

The design is based on Texas Instruments' ADS54J60 Analog-to-Digital converter and Texas Instruments' DAC39J84 Digital-to-Analog converter.

The sample clock can be supplied externally through a coaxial connection or supplied by an internal clock source (optionally locked to an external reference) for multi-channel synchronization. An external trigger input is available for timing synchronization.

The FMC121 is mechanically and electrically compliant with the FMC standard (ANSI/VITA 57.1). The card connects to an FPGA carrier card through a standard high-pin count (HPC) connector.

Front panel I/O can optionally be populated with MMCX or SSMC coaxial connectors. Analog I/O is DC coupled.

The FMC121 is designed to be used in convection or conduction cooled environments. When paired with the latest FPGA carrier cards such as the Abaco Systems PC821 with Xilinx Ultrascale technology, customers can develop innovative high performance algorithms on an industry standard platform.
