1.0 INTRODUCTION
The UT200SpW4RTR-EVB is a 4-Port SpaceWire Router evaluation board designed to allow the system designer access to all
the features of the UT200SpW4RTR 4-Port router as defined in the datasheet (www.aeroflex.com/spacewire). The 4-Port
router is capable of operating at data rates from 10 to 200 Mbps. A parallel host interface is accessible through an onboard
FPGA. The Evaluation board can also be plugged into the Aeroflex Gaisler LEON 3-FT evaluation board, further expanding
functionality of the UT200SpW4RTR-EVB.
The UT200SpW4RTR router implements a non-blocking crosspoint switch and a "Round Robin" arbitration scheme allowing
all five receive ports access to all five transmit ports. Path and logical addressing are supported (Per ECSS-E-ST-50- 12C) and
lookup table storage is replicated five times giving each receive port a dedicated block of memory for logical addressing.
Configuration of lookup tables, as well as, access to internal registers may occur through any of the five ports using a simple
configuration protocol. A group adaptive function is also provided for two ports when implementing logical addressing.
Each of the four SpaceWire ports is capable of running at an independent speed. The clocking of the 4-port router is provided
by Aeroflex's Clock Network Manager II. This allows the users systems to be configured with nodes/instruments running at
different speeds.
2.0 SCOPE
This document describes the features and necessary steps to set-up and operate the Aeroflex SpaceWire 4-port Router
Evaluation Board. It is recommended that the user be familiar with the UT200SpW4RTR 4-Port SpaceWire Router datasheet.
