LXD41K0 Industrial-Grade Isolated digital I/O FMC
The LXD41K0 FMC (FPGA Mezzanine Card) provides a robust, galvanically isolated digital interface for FPGA platforms. It supports 16 digital inputs, 16 digital outputs, one clock output, and isolated trigger input and output channels, delivering a total of 17 inputs and 18 outputs via an industry-standard 68-pin VHDCI connector.
All I/O signals use the 3.3 V LVCMOS standard.
Galvanic isolation
Unlike conventional FMC I/O modules, our isolated FMC products are specifically designed for high-voltage, high common-mode transient environments. Integrated galvanic isolation and high-CMTI digital isolators protect the FPGA and eliminate ground loop and EMC issues, simplifying system integration in demanding industrial applications.
18 bits inputs and 17 bits output
A total of 18 inputs and 17 outputs are available on the VHDCI 68-pin front-panel connector.
Stackable FMC
The LXD41K0 is part of the Logic-X stackable FMC product line, enabling flexible and scalable configurations.
An optional bottom-side FMC stacking connector routes the Lower LA[16:0] signals from the stack connector to the LA[33:17] of the top FMC connector.
As a result two LXD41K0 modules can be stacked on a single LPC site, creating double the isolated digital I/O ports.
Other FMC modules requiring only LA[16:0] signals can also be combined in mixed configurations. This architecture enables scalable channel counts without requiring additional FMC sites.
