Project goal

• Development of a high sensitivity / high speed
  CCD camera for microscopy
• TI TC253SPD-BD 656x496 pixel
• Continuous recording to analyze data after
  experiment
• PC system with RAID for data storage
• High flexibility to adapt camera for different
  needs in different experiments
• FPGA at the camera front-end for CCD control
• and transmission

Design decisions
12.0V

• 5V Analog Power
• CCD needs lots of
• different voltages
• to operate
• 5V Digital Power
• 2.5V and 3.3V for FPGA
• 12.0V and 3.0V for Peltier cooler

Separation of digital and analog power planes to
avoid noise introduction

Physical design decisions restrictions

• Peltier controller will be mounted on a socket on
  top of the board to save space
• CCD needs to be placed
• at the end of the board
• not to block the viewer
• Mounting holes need
• to be specified in order to manufacture a stand
