Main Components
JTAG Interfaces
The JTAG chain is separated into three segments. One segment contains the CPLD devices, a
second contains the AMCC 440GX processor and the last one contains the remaining JTAG
capable chips.
It is possible to connect to only the segments that are appropriate for a specific software tool.
An adapter board is needed to connect to the correct taps of the chain, and to provide connectors
that are compatible with the tools connector. For more information please contact VMETRO.
Temperature Sensors
Temperature sensors are very useful when monitoring applications during extreme conditions.
Several temperature sensors are located on the board in order to monitor the variation of
temperature. Four sensors are on the component side: one close to the bottom of the board, one
close to the top of the board and two located in the middle of the board.
These sensors require additional software, contact VMETRO for information.
Power Supplies (DC-DC converters)
The main source of power is the 5V supplied from the VME backplane. The following voltages are
generated: 3.3V, 2.5V, 1.8V and 1.5V.
