Monaco Technical Reference Spectrum Signal Processing
Introduction
4 Part Number 500-00191
Revision 2.00
1.4. General Bus Architecture
The following block diagram shows the main components of the Monaco board.
1.5. On-Board Power Supply
There is an on-board high-efficiency DC-DC power converter that supplies +2.5V and
+3.3V power to the board from the VME 5V supply. The circuit efficiency is
approximately 90%. The +3.3V supply is available to the PEM and PMC sites, as well as
+5V and ±12V. Up to 16.5 Watts is available from the +3.3V supply for the PEM and
PMC sites. The combined +3.3V current consumption of modules on these sites must not
exceed 5 Amps.
When adding modules to the Monaco board, ensure that the power requirements for the
modules are within the specified limits, and that the system power supply and cooling are
sufficient to meet the added requirements.
