5.0 FEATURES AND GENERAL OPERATION
The Aeroflex 4-Port SpaceWire Router evaluation board is designed to provide the user a flexible means to configure, control,
access, and route data through the UT200SpW4RTR device. Power to the board may be provided through the J9 connector on
the GR-UT699 CPCI Development Board or through the BNC connectors. Only one power source should be used at a time.
Clocking of the board is done via the UT7R2XLR816 Clock Network Manager. The UT7R2XLR816 can be configured using
the on board FPGA (Xilinx V2) or using the designated jumpers. The user is encouraged to download the UT7R2XLR816
Clock Network Manager Software GUI available at www.aeroflex.com/clocks
and familiarize themselves with the
UT7R2XLR816 Clock Network Manager datasheet.
The 4-Port router device can be accessed using any of the four SpaceWire ports or through the V2 FPGA that is connected to
the Host port of the router. The FPGA on the board can be controlled and programmed by using either the JTAG connector or
using the LEON 3FT on the GR-UT699 Evaluation board. All of these features are detailed in the following sections.
