Description
The high-resolution VITA CMOS image sensor family features global and rolling shutter mode. The on-chip programmable
state machine controls the sensor array and enables high flexibility with changes in operation modes and 32 frame-to-frame
configurable Regions-of-Interest (ROI). The 5T pixel on a 4.5 mm pitch enables pipelining of integration and read-out in both
triggered and un-triggered global shutter mode.
A second pipeline stage provides a maximum frame rate increase by allowing the sensor to run in Zero-ROT mode. The roller
shutter mode supports correlated double sampling, reducing temporal noise by approximately 3 dB. The sensor has on-chip
programmable gain amplifiers and 10-bit A/D converters. The image’s black level has an automatic calibration with adjustable
user programmable offset. The image data interface consists of 32 or 16 LVDS channels with additional clock and
synchronization channels in parallel, each running at 680 Mbps.
The high-resolution VITA family is packaged in a ceramic 355-pin PGA package and is available in a monochrome and color
version.

Power Distribution Network
A power distribution network (PDN) is designed to ensure
proper power management to the VITA sensor. Table 7
provides the recommended power supplies for the VITA
power management. Please refer to the AN65466 for
recommended linear regulator selection, decoupling
capacitor network and BOM for the power distribution
network.

• VDD_sel can be combined with either VDDD_33 or VDDA_33
• VDD_respd and VDD_trans can be grouped together as VDD_42
• gnd_respd is be designed to be a 7 mA sinking supply, but can be tied to ground with no impact to image quality
Color Filter Array
The VITA color sensor is processed with a Bayer RGB
color pattern as shown in Figure 2. Pixel (0,0) has a red filter
situated to the bottom left. Green1 and green2 have a slightly
different spectral response due to (optical) cross talk from
neighboring pixels. Green1 pixels are located on a green-red
row, green2 pixels are located on a blue-green row.
Figure 3 depicts the spectral response for the mono and
color devices. Figure 4 shows the photovoltaic response for
the VITA.

Rolling Shutter Mode
The sensor also supports the rolling shutter mode. The
shutter mechanism is an electronic rolling shutter and the
sensor operates in streaming mode similar to a video. This
mechanism is controlled by the on-chip sequencer logic.
There are two Y pointers, as indicated in Figure 10. One of
them points to the row that is to be reset for rolling shutter
operation and the other points to the row to be read out.
Functionally, a row is reset first and selected for readout
later. The time elapsed between these two operations is the
exposure time.
Figure 10 schematically indicates the relative shift of the
integration times of different lines during rolling shutter
operation. Each row is read and reset sequentially, as
described in the previous paragraph. Each row in a particular
frame is integrated for the same time, but all lines in a frame
‘see’ a different stare time. Therefore, fast horizontal
moving objects in the field of view give rise to motion
artifacts in the image; this is an unavoidable property of a
rolling shutter.
In rolling shutter mode, a second pointer indicates the
rows that need to be reset for the rolling shutter mechanism.
The distance between the reset pointer and the readout
pointer determines the integration time.
The VITA 16K/12K supports dynamic exposure time
updates without artifacts or interrupting the image data
stream.
