OPERATIONAL SETTINGS
The Imager board is configured to operate the KAI-4011/KAI-4021 CCD image sensors under the following operating
conditions:
BIAS VOLTAGES
The following voltages are fixed, or adjusted with a potentiometer as noted. The nominal values listed in Table 3 were
correct at the time of this document's publication, but may be subject to change; refer to the KAI-4011/KAI-4021 device
specification.
Description
Left Output Amplifier Supply
Right Output Amplifier Supply
Reset Drain
ESD Protection
Substrate
Output Gate Left
Output Gate Right
NOTES:
1.
If the CCD is to be operated in single output mode only (VOUT_LEFT) the unused output amplifier supply can be tied to ground to conserve
power by not populating R71, R72 and C76 and by replacing C75 with a 0 ohm resistor.
2.
The Output Gate signals VOGL and VOGR may be controlled independently, or, by installing R28 and R33 and removing R29, may be set to
the same potential, controlled by R11.
3.
The Min and Max voltages in the table indicate the imager board potentiometer adjustable voltage range. These values may exceed the
specified CCD operating conditions. See the KAI-4011/KAI-4021 device specification for details.
CLOCK VOLTAGES
The following clock voltage levels are fixed, or adjusted with a potentiometer as noted. The nominal values listed in Table
4 were correct at the time of this document's publication, but may be subject to change; refer to the KAI-4011/KAI-4021
device specification.
Description
Horizontal CCD Clock
Vertical CCD Clock
Reset Clock
Fast Dump Clock
NOTES:
1.
The H1A_CCD, H1B_CCD, H2A_CCD, and H2B_CCD low levels are controlled by the same potentiometer (R147).
2.
The H1A_CCD, H1B_CCD, H2A_CCD, and H2B_CCD high levels are controlled by the same potentiometer (R127).
3.
V1_CCD and V2_CCD low levels are controlled by the same potentiometer (R40)
4.
V1_CCD and V2_CCD mid levels are controlled by the same potentiometer (R66)
5.
FDG is used to flush the device when operated in Still Mode.
