1.Pre-amp circuit inside
the CCD header
Four channel single input and differential output pre_amp circuit has been built for NAOMI CCD header. There is also a receiver board built for SDSU controller to enable it to convert the differential signal into single-ended signal. At present system, the pre-amp circuit and the receiver circuit are not used, there are straight line sold on board to pass the circuit.
(U:\sw4\atc_naomi\naomi-0.1\docs\camera\naomi_ICD_parthree.doc ). See enclosed diagram for details (naomipre.prj -Protel file)
2. Pre-amp circuit PCB
layout
there are different layout for master and slave CCD respectively.
(U:\sw4\atc_naomi\naomi-0.1\docs\camera\naomi_ICD_parthree.doc).
See enclosed diagram for details. (bdlayout.vsd-visio file, J1525ch3.pdf-acrobat file)
3. Ground arrangement
for the controller
(U:\sw4\atc_naomi\naomi-0.1\docs\camera\naomi_ICD_parthree.doc). See enclosed diagram for details. (naomicable.xls- Excel file)
4. Cabling for video
bias and clock from SDSU controller to the CCD header
(U:\sw4\atc_naomi\naomi-0.1\docs\camera\naomi_ICD_parthree.doc). See enclosed diagram for details.(naomicable.xls- Excel file)
5. The new set and old
set video cables connection inside SDSU controller
