LD_X
Input
Digital input. Latch address (A0…A9) to X-register (0 = track, 1 = hold).
10
VDDA
Supply
Analog power supply of the imager (typical 5V).
11
GNDD
Ground
Digital ground of the imager.
12
GNDA
Ground
Analog ground of the imager.
13
CLK_X
Input
Digital input. Clock X-register (output valid & stable when CLK_X is high).
14
RESET_DS
Input
Digital input (high active). Resets row indicated by Y-address (see sensor
timing diagram).
RESET_DS is used for dual-slope integration (see FAQ).
GND is used for normal operation.
15
VDDD
Supply
Digital supply of the image sensor.
16
RESET
Input
Digital input (high active). Resets row indicated by Y-address (see sensor
timing diagram).
17
S
Input
Digital input (high active). Control signal for column amplifier (see sensor
timing diagram).
18
R
Input
Digital input (high active). Control signal for column amplifier (see sensor
timing diagram).
19
NBIAS_DEC
Input
Analog input. Biasing of address decoder.
Connect with 100 k
to VDDA and decouple with 100 to GND.
20
A_IN2
Input
Additional analog inputs. For proper conversion with on-chip ADC, the
input signal must lie within the output signal range of the image sensor
(approximately +2V to +4V).
21
A_IN3
Input
22
A_IN1
Input
23
A_SEL1
Input
Selection of analog channel: '00' selects image sensor ('01' selects A_IN1,
'10' A_IN2, and '11' A_IN3).
24
A_SEL0
Input
25
NBIAS_OAMP
Input
Analog input. Bias of output amplifier (speed/power control).
Connect with 100 k
to VDDA and decouple with 100 nF to GND for 12.5
MHz output rate (lower resistor values yield higher maximal pixel rates at
the cost of extra power dissipation).
26
PBIAS
Input
Analog input. Biasing of the multiplexer circuitry.
Connect with 20 k
ω to GND and decouple with 100 nF to VDD.
27
G1
Input
Digital input. Select output amplifier gain value: G0 = LSB, G1 = MSB ('00'
= unity gain, '01' = x2, '10'= x4, '11'=x8).
28
G0
Input
29
CAL
Input
Digital input (active high). Initialization of output amplifier. Output amplifier
outputs BLACKREF in unity gain mode when CAL is high (1).
Apply pulse pattern (see sensor timing diagram).
30
OUT
Output
Analog Output Video Signal. Connected to the analog input of the internal
(pin 52) 10-bit ADC or an external ADC.
31
BLACKREF
Input
Analog input. Control voltage for output signal offset level. Buffered
on-chip, the reference level can be generated by a 100 k
ω resistive divider.
Connect to 2V DC for use with on-chip ADC.
32
VDDA
Supply
Analog power supply of image core (typical 5V).
33
VDDD
Supply
Digital power supply of image core (typical 5V).
