FMC144 – 4-channel 16-bit 370MSPS ADC & 4-channel 16-bit 2.5GSPS DAC | HPC Board

4-channel 16-bit 370MSPS A/D
4-channel 16-bit 2.5GSPS D/A
FMC VITA 57.1 Compliant

The FMC144 is an analog-to-digital (A/D) and digital-to-analog (D/A) FMC daughter card that provides four 16-bit A/D channels at 370MSPS and four 16-bit D/A channels at 2.5GSPS which can be clocked by an internal clock source (optionally locked to an external reference) or by an externally-supplied sample clock.

 

The design is based on Texas Instrument’s ADC16DX370 dual-channel 16-bit 370MSPS ADC and DAC38J84 quad-channel 16-bit 2.5GSPS DAC. The analog signal inputs are either AC or DC-coupled and connected to MMCX/SSMC coax connectors on the front panel. The FMC144 is ideal for applications where limited space is available such as RADAR/SONAR, wireless telecommunications, and aerospace test and measurement instruments.

 

The FMC144 also features a JESD204B serial interface to provide a simplified high-speed interface between the data converters and the FPGA with a minimum of digital IO on the board. This module therefore delivers high-bandwidth connectivity suited for a wide range of calculation-heavy FPGA-based applications such as beamforming, direction finding, and software-defined radio (SDR)
