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

Training project to learn about Power Delivery Network measurements and simulations. With a PDN usually the power distribution on a PCB is meant. This project describes a PCB with additional connectors to measure the power distribution quality. More info at the Wiki page

FMC 4 channel Serial link transceiver with differential LEMO connectors. Differential signalling with Vh=3.3V and Vl=1.7V. More info at the Wiki page

White Rabbit Switch WRS-3/18 (hardware version 3.4) with modified SCB prepared for the low-jitter daughterboard and modified backplane. Commercially available. More info at the Wiki page

TiCkS is a flexible White Rabbit based time-stamping board. It is based on the SPEC board developed for the CTA collaboration. It provides an interface to a CTA camera (Inputs: Read-out Trigger signals, Busy Trigger), (Outputs: PPS signal , 10MHz clock, External trigger signal).

PUMA (Plataforma Utilizada para el Muestreo de Arapuca) is a multi-channel digitizer designed to instrument the photon detection system for the DUNE Photon Detection System. However, it may be useful for other applications that require 40 - 64 channels of 14-bit digitzier sampling at 10MSample/s - 65MSample/s. PUMA is based on the digitizer designed for the SoLiD short baseline reactor neutrino detector. It is designed to be connected to external signal conditioning modules, which are controlled by I2C.

A web based commander based on Node.JS for the HDLMake tool.

This project focuses on performing with high precision the core WR PTP calculations in fixed-point arithmetic. This will ensure uniform input parameters, code and precision across all WR implementations.

This project hosts compliance tests dedicated for WR devices and based on the ATTEST framework available from Veryx Technologies. To use the material available in this project, the ATTEST framework needs to be purchased.

COM Express based PXIe system controller. COM Express Compact Pin-out type 6, 16-lane PCIe GEN3. PXIe trigger line on front-panel. More info at the Wiki page

This is a collection of simple macro implementations for Microsemi's ProASIC3 FPGAs to allow simulating post-synthesis designs using GHDL.
