1.2 About WR ZEN Family
The White Rabbit ZEN Time Providers (aka. WR-ZEN TP) are high performance timing nodes family
whose design is based on the Xilinx Serie-7 FPGAs that combines an Artix-FPGA with a Dual-Core
ARM.
It is composed of the next products:
•
WR-ZEN TP
•
WR-ZEN TP-32BNC
•
WR-ZEN TP-FL
They are the versatile standalone nodes that provide WR features (i.e., sub-nanosecond time
synchronization in a network with thousands of nodes) controlled by a user-friendly Linux OS
which runs on a dual ARM processor.
The WR-ZEN TP easily distributes time and frequency to other equipment by implementing
standard timing protocols such as PTP, NTP and IRIG-B. The WR-ZEN TP combines ultra-stable
clocks with low jitter and temperature compensated clock resources to enhance its
synchronization accuracy. In addition, it allows integrating FMC cards.
Its robustness to failure is one of its key features thanks to redundant dual power supply and a
fanless design.
It is also worth mentioning its ability to support daisy chain configurations in which each WR-ZEN
TP device synchronizes with another WR-ZEN TP belonging to a higher order in the hierarchy
level. At the same time, it provides synchronization to a lower level.
