Functional Description

OVERVIEW
1.1
The LM9617 contains a CMOS active pixel array consisting of
648 rows by 488 columns. This active region is surrounded by 8
columns and 8 rows of optically shielded (black) pixels as shown
in Figure.

At the beginning of a given integration time the on-board timing
and control circuit will reset every pixel in the array one row at a
time as shown in Figure 8. Note that all pixels in the same row
are simultaneously reset, but not all pixels in the array.

CMOS APS Row and Column addressing scheme
At the end of the integration time, the timing and control circuit
will address each row and simultaneously transfer the integrated
value of the pixel to a correlated double sampling circuit and
then to a shift register as shown in Figure 8.
Once the correlated double sampled data has been loaded into
the shift register, the timing and control circuit will shift them out
one pixel at a time starting with column “a”.
The pixel data is then fed into an analog video amplifier, where a
user programmed gain is applied .
After gain adjustment the analog value of each pixel is con-
verted to a 12 bit digital data as shown in Figure 9.

The digital pixel data is further processed to:
remove defects due to bad pixels,
compensate black level, before being framed and presented
on the digital output port. (see Figure 10).

1.2
The programming, control and status monitoring of the LM9617
is achieved through a two wire I
2
C compatible serial bus. In
addition, a slave address pin is provided (see Figure 11).
Program and Control Interfaces
Figure 11. Control Interface to the LM9617.
Additional control and status pins: snapshot and external event
synchronization are provided allowing the latency of the serial
control port to be bypassed during single frame capture. An
interrupt request pin is also available allowing complex snapshot
operations to be controlled via an external micro-processor (see
Figure 12).
