Designated LXD31K4, it is ideal for edge processing, high-speed data acquisition and playback, software-defined radio (SDR), and other applications requiring high-bandwidth conversion between the analog and digital domains. The board can be integrated as-is into an embedded system or used during the development and prototyping of a mixed-signal SoC or ASIC. Furthermore, it is supplied with a reference design to help engineers accelerate their development programs.
Logic-X's use of LVDS for data interfaces on the LXD31K4 means users can easily integrate the board with an FPGA without having to purchase and embed JESD204B-compatible interface cores for converters and receivers. This approach shortens system development/prototyping time and reduces overall project risk.
The LXD31K4 offers four A/D channels, each with a data conversion rate of up to 310 megasamples per second (Msps), and four D/A channels, each with a raw conversion rate of up to 310Msps which (with interpolation of up to 4x - set by the user) can produce a signal with a refresh rate of up to 1.24GHz.
The eight channels are 16-bit precise and offer best-in-class signal-to-noise ratio (SNR). Furthermore, the card is available with either a DC or AC front end, which determines the bandwidth an input channel can accept, as well as the bandwidth the card can produce on an output channel.
"With recent advances in machine learning and artificial intelligence, there is a growing need for high-bandwidth edge processing," says Erik Barhorst, CEO of Logic-X. "Furthermore, in most cases, multiple input and output channels are required at the edge, and we launched the LXD31K4 in direct response to market demand.".
Barhorst, who is also the lead architect of the LXD31K4, goes on to say that the new board was designed with engineers in mind. For example, the LVDS pinout is configured to work with most "partial implementations" of the high-pin-count connectors on Xilinx development boards, as well as on Logic-X's FMC FPGA motherboards.

A 2-in-2-out version of Logic-X's latest FMC is also available. Designated the LXD31K2, it also features 16-bit resolution, uses LVDS, and can be ordered with either a DC or AC front end. Other options for both the LXD31K4 and LXD31K2 include the operating temperature range (standard 0 to 85°C or industrial -40 to 85°C) and whether or not it is coated (with a coating conforming to MIL-I-46058-C).
The reference design supplied with the LXD31K4 (and the LXD31K2) comprises a Vivado IP integrator project and IP cores that can be controlled from a software application via Ethernet or PCI Express (PCIe), plus detailed documentation.
The LXD31K4 and LXD31K2 are currently being tested and are expected to be available in volume in the fourth quarter of 2021.
About Logic-X
Founded in 2018 and headquartered in Europe, Logic-X develops, manufactures and markets a wide range of high-performance Adaptive Compute Acceleration Platforms (ACAPs) and sensor processing modules designed to solve the challenges of complex embedded and edge processing requirements.
Leveraging its extensive experience in programmable logic and data conversion, Logic-X offers its customers access to the latest sensor processing technologies, ACAP, MPSOC and FPGA, in both commercial off-the-shelf (COTS) and customer-specific (MCOTS) modules, making it easy to integrate them into system designs.
Logic-X products allow customers to focus clearly on their end applications instead of spending time developing custom processing platforms, significantly improving time to market and reducing overall risk.
