Radiation-tolerant AC/DC power supply unit (PSU). In: 230VAC, 50Hz, Out: +12V, 8.33A (100W) and +5V, 2A (10W). Possibility for redundancy. The design is CompactPCI compatible. Part of DIOT project.

FmcAdc100M14b4cha is a 4 channel 100MSPS 14 bit ADC low pin count FPGA Mezzanine Card (VITA 57). More info at the Wiki page

DIOT 3U crate mechanics and backplane compliant with CompactPCI-Serial standard.

A Precise Time Protocol (PTP, IEEE 1588) software stack whose single source code can be compiled for many architectures (POSIX systems, WR switch, WR node, ...) and which is easily extensible.

A White Rabbit compliant Network Interface Card (NIC) based on the SPEC and the DIO FMC. This project hosts the HDL and associated software to configure the SPEC so it behaves as a NIC under the Linux OS.

FmcDIO5chTTLa is a 5-bit port digital IO card in FMC form-factor. Each single-bit port can be configured individually as input or output. The I/Os on LEMO 00 connectors are TTL compatible. Commercially available. More info at the Wiki page

This project guides new users to start in the White Rabbit “World” with simple experiments. The starting kit uses two SPEC + FMC-DIO cards. Each node allows basic operations such as input timestamping or programmable output pulse generation. Additionally, specific software and gateware layers allow to use it as a standard network interface card implementing the White Rabbit technology functionalities.

A fine delay generator in FMC format with 1 input and 4 outputs. The resolution is 1 ns. Commercially available. More info at the Wiki page

The DAPHNE front end board is a piece of hardware that digitizes the output signal from one of the systems of the far detector in the DUNE experiment. For more information, see the wiki

A simple 4-lane PCIe carrier for a low pin count FPGA Mezzanine Card (VITA 57). It supports the White Rabbit timing and control network. Commercially available. Linux and Labview drivers available for some mezzanine cards. More info at the Wiki page

A collection of platform-independent cores such as memories, synchronizer circuits and Wishbone cores.

Tool for generating multi-purpose makefiles for FPGA projects.

Main features:

makefile generation for: fetching modules from repositories simulating HDL projects synthesizing HDL projects synthesizing projects remotely (keeping your local resources free) generating multi-vendor project files (no clicking in the IDE!) many other things without involving make and makefiles

Hdlmake supports modularity, scalability, revision control systems. Hdlmake can be run on any Linux or Windows machine with any HDL More info at the Wiki page

This is a PCB-design + Arduino firmware for an Ethernet-controlled 1:8 RF-multiplexer. It allows selecting as output one of eight input-channels, as commonly used e.g. in timing-laboratories when one wants to measure many RF-sources (clock outputs like 1PPS or 10MHz) with a single instrument (frequency or time-interval counter). The design is for two independent MUX-boards to fit in a 1U 19” rack enclosure. For more information, see the wiki
