MLE is shipping to the first customers the Dormouse White Rabbit FPGA Mezzanine Card (FMC), specifically designed to implement White Rabbit technology for highly accurate time and frequency distribution Ethernet-based networks.
The Dormouse White Rabbit FPGA FMC features tunable oscillators that are required to deploy and operate White Rabbit, an open-source FPGA-based implementation of Precision Time Protocol 2.1 (PTP v2.1). With the Dormouse White Rabbit FPGA FMC, White Rabbit implementation can achieve sub-nanosecond accuracy of the PTP v2.1 high-accuracy profile, making it an ideal solution for building a time and frequency distribution network for applications like data center, radar, neutrino telescope, automotive, or control systems.
The Dormouse White Rabbit FPGA FMC provides capabilities to generate LF and RF reference clocks derived from a White Rabbit network. For these tasks a high performance OCXO (DOT050V), two programmable and tunable oscillators (SiT3521, Si549) and a flexible PLL (HMC7044) are available for use on the card.
In addition to the clocking infrastructure, an SFP+ interface provides 1 GbE / White Rabbit connectivity, which enables boards that do not provide an SFP+ interface.
