MMC firmware written in C, running on a microcontroller inside the board. Written first for the AFC boards. This firmware is thought to be generic enough so other AMC boards could reuse a large part of it. For now, the only "port" is for the LPC1764 chip, but more are planned.

A VME rear transition module providing fibre-optic and electrical (RS485) inputs and outputs. Uses the CONV-TTL-RS485 as front-module. More info at the Wiki page

High performance pulse and frequency distribution amplifier for time and frequency metrology. The pulse distribution board is an 1:8-channel (1 Hz and up) logic-level distribution amplifier, while the frequency distribution board is an 1:8-channel sine-wave (1-30 MHz) distribution amplifier. Two 1:8 boards fit side-by-sides in a 1U 19" rack enclosure, with either BNC or SMA connectors.

A simple 4-lane PCIe carrier for a FPGA Mezzanine Card (VITA 57). It supports the White Rabbit timing and control network. More info at the Wiki page

VHDL coding style document to be used at ohwr.org The project contains also a tool to automatically check the coding style. 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

The TimIQ system is an IQ modulator allowing to phase shift a radio frequency clock with a resolution of 40 fs and an accuracy of 8 ps. Software.

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.
