Appendix #appelectronics_design#1673>: Electronics Design

  This appendix contains block diagrams of the CUBIC electronics plus detailed drawings of our electronics interfaces with SAC-B . Detailed electronic drawings are available in a separate document entitled ``CUBIC Electronics Data Package''. This appendix contains the following:

1. Overall block diagram of CUBIC electronics.
2. SAC-B Interface connector pinouts.
3. Image Control Processor board block diagram.
4. Spacecraft Communications Interface board block diagram.
5. Camera Control/Interface board block diagram.
6. Clock Driver Board block diagram.
7. CUBIC analog electronics block diagram.
8. Detailed schematics for our SAC-B electronics interfaces:
   1. Pulse Relay Command channels.
   2. Reset Pulse Command channel.
   3. Data Collection On/Off Pulse Command channel (spare).
   4. Serial Command channel.
   5. Science data serial channel.
   6. Serial Housekeeping channel.
   7. Bilevel Housekeeping channel.

This is a subset of the complete CUBIC Electronics Data Package. In the event of any discrepancy between this Appendix and the Electronics Data Package, the latter is more authoritative and takes precedence.
