AR0331
AR0331 1/3‐Inch 3.1 Mp/Full
HD Digital Image Sensor
General Description
The ON Semiconductor AR0331 is a 1/3-inch CMOS digital image
sensor with an active-pixel array of 2048 (H) x 1536 (V). It captures
images in either linear or high dynamic range modes, with a
rolling-shutter readout. It includes sophisticated camera functions
such as in-pixel binning, windowing and both video and single frame
modes. It is designed for both low light and high dynamic range scene
performance. It is programmable through a simple two-wire serial
interface. The AR0331 produces extraordinarily clear, sharp digital
pictures, and its ability to capture both continuous video and single
frames makes it the perfect choice for a wide range of applications,
including surveillance and HD video.
The ON Semiconductor AR0331 can be operated in its default mode
or programmed for frame size, exposure, gain, and other parameters.
The default mode output is a 1080p-resolution image at 60 frames per
second (fps). In linear mode, it outputs 12-bit or 10-bit A-Law
compressed raw data, using either the parallel or serial (HiSPi) output
ports. In high dynamic range mode, it outputs 12-bit compressed data
using parallel output. In HiSPi mode, 12- or 14-bit compressed, or
16-bit linearized data may be output. The device may be operated in
video (master) mode or in single frame trigger mode.
FRAME_VALID and LINE_VALID signals are output on dedicated
pins, along with a synchronized pixel clock in parallel mode.
The AR0331 includes additional features to allow application-
specific tuning: windowing and offset, auto black level correction, and
on-board temperature sensor. Optional register information and
histogram statistic information can be embedded in the first and last 2
lines of the image frame.
The sensor is designed to operate in a wide temperature range
(–30°C to +85°C).

AR0331
FUNCTIONAL OVERVIEW
The AR0331 is a progressive-scan sensor that generates
a stream of pixel data at a constant frame rate. It uses an
on-chip, phase-locked loop (PLL) that can be optionally
enabled to generate all internal clocks from a single master
ADC data
12
input clock running between 6 and 48 MHz. The maximum
output pixel rate is 148.5 Mp/s, corresponding to a clock rate
of 74.25 MHz. Figure 1 shows a block diagram of the sensor.

Figure 1. Block Diagram
User interaction with the sensor is through the two-wire
serial bus, which communicates with the array control,
analog signal chain, and digital signal chain. The core of the
sensor is a 3.1 Mp Active-pixel Sensor array. The timing and
control circuitry sequences through the rows of the array,
resetting and then reading each row in turn. In the time
interval between resetting a row and reading that row, the
pixels in the row integrate incident light. The exposure is
controlled by varying the time interval between reset and
readout. Once a row has been read, the data from the
columns is sequenced through an analog signal chain
(providing offset correction and gain), and then through an
analog-to-digital converter (ADC). The output from the
ADC is a 12-bit value for each pixel in the array. The ADC
output passes through a digital processing signal chain
(which provides further data path corrections and applies
digital gain). The sensor also offers a high dynamic range
mode of operation where multiple images are combined
on-chip to produce a single image at 16-bit per pixel value.
A compression mode is further offered to allow the 16-bit
pixel value to be transmitted to the host system as a 12-bit
value with close to zero loss in image quality.

Notes:
1.
2.
3.
4.
All power supplies should be adequately decoupled.
ON Semiconductor recommends a resistor value of 1.5 kΩ, but a greater value may be used for slower two-wire speed.
The parallel interface output pads can be left unconnected if the serial output interface is used.
ON Semiconductor recommends that 0.1
μF
and 10
μF
decoupling capacitors for each power supply
are mounted as close as possible to the pad. Actual values and results may vary depending on layout and design
considerations. Refer to the AR0331 demo headboard schematics for circuit recommendations.
5. ON Semiconductor recommends that analog power planes are placed in a manner such that coupling
with the digital power planes is minimized.
6. I/O signals voltage must be configured to match VDD_IO voltage to minimize any leakage currents.
