FMC254

Quad ADC 12-bit @ 1.6 GSPS FMC+ Module

An ADC/DAC FMC module is an FPGA Mezzanine Card that adds high-speed analog input and/or analog output channels to an FPGA carrier board.

ADC means analog-to-digital converter. It converts real-world analog signals into digital samples the FPGA can process.
DAC means digital-to-analog converter. It converts digital data from the FPGA into an analog waveform.

The module usually includes:

One or more ADC or DAC channels
Analog front-end circuitry
Clock and synchronization inputs
Trigger connections
FMC or FMC+ connector
Sometimes JESD204B or JESD204C high-speed serial interfaces
Front-panel RF connectors such as SMA

Typical applications include:

Software-defined radio
Radar
Oscilloscopes and waveform generators
Communications testing
Scientific data acquisition
Feedback and control systems

Description:

FMC254 is an FPGA Mezzanine Card (FMC+) per VITA 57.4 specification. The board has quad TI ADC12SJ1600 which provides 12-bit resolution at 1.6 GSPS. This ADC is ideal for light detection and ranging (LiDAR) systems. The full-power input bandwidth also enables direct RF sampling of L-band and S-band.

FMC254 provides four single ADC to allow interleaving among the four ADC. This is accomplished by skewing the sampling clock property among the four ADC.

The four analog input, clock and trigger interfaces of FMC254 are routed via SSMC connectors. The internal clock frequency is programmable and the clock is capable of locking to an external reference.
