AR0234CS

Advance Information

1/2.6-inch 2.3 Mp CMOS

Digital Image Sensor

with Global Shutter

Description

The AR0234CS is a 1/2.6−inch 2Mp CMOS digital image sensor

with an active−pixel array of 1920 (H) x 1200 (V). It incorporates a

new innovative global shutter pixel design optimized for accurate and

fast capture of moving scenes at full resolution 120 frame per second.

The sensor produces clear, low noise images in both low−light and

bright scenes. It includes sophisticated camera functions such as auto

exposure control, windowing, row skip mode, column−skip mode,

pixel−binning and both video and single frame modes. It is

programmable through a simple two−wire serial interface. The

AR0234CS produces extraordinarily clear, sharp digital pictures with

an industry leading Global Shutter Efficiency, and its ability to capture

both continuous video and single frames makes it the perfect choice

for a wide range of applications, including scanning and industrial

inspection.

GENERAL DESCRIPTION

The ON Semiconductor AR0234CS can be operated in its

default mode or programmed for frame size, exposure, gain,

and other parameters. The default mode output is

a full−resolution image at 120 frames per second (fps). It

outputs 10−bit raw data using parallel output ports or 10−bit

or 8−bit using serial (MIPI) output ports. The device may be

operated in video (master) mode or in frame trigger mode.

FRAME_VALID and LINE_VALID signals are output on

dedicated pins, along with a synchronized pixel clock.

A dedicated FLASH pin can be programmed to control

external LED or flash exposure illumination.

The AR0234CS includes additional features to allow

application−specific tuning: windowing, adjustable

auto−exposure control, auto black level correction,

on−board temperature sensor, row−skip and column−skip

modes and binning modes.

The sensor is designed to operate in a wide ambient

temperature range (–40°C to +85°C).

FUNCTIONAL OVERVIEW

The AR0234CS 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 input clock running between 6 and 64 MHz.

The maximum output pixel rate is 90 Mp/s, corresponding

to a clock rate of 90 MHz. Figure 1 shows a block diagram

of the sensor.

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 2.3 Mp Active−Pixel Sensor array. The

AR0234CS features global shutter technology for accurate

capture of moving images. The exposure of the entire array

is controlled by programming the integration time by

store signal at the pixel. Once a row readout sequence has

been initiated, each pixel’s stored signal is then transfered

through the analog signal chain (providing offset and gain)

and then through each column analog to−digital converter

(ADC). The output from the ADC is a 10−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 pixel data are

output at a rate of up to 90 Mp/s, in parallel to frame and line

synchronization signals.

FEATURES OVERVIEW

The AR0234CS Global Shutter sensor has a wide array of

features to enhance functionality and to increase versatility.

A summary of features follows.

• 3.0 mm Global Shutter Pixel

To improve the low light performance and to capture

the moving images accurately a large (3.0 mm) global

shutter pixel is implemented for better image

optimization.

• Operating Modes

The AR0234CS works in master (video), Slave/ Trigger

(single frame), or Auto Trigger modes. In master mode,

the sensor generates the integration and readout timing.

In Slave/trigger mode, it accepts a trigger from external

host to start exposure, then generates the exposure and

readout timing. The external trigger signal allows for

precise control of frame rate and register change

updates. The exposure time is programmed through the

two−wire serial interface for both modes.

• Window Control

Configurable window size and blanking times allow

a wide range of resolutions and frame rates. Digital

binning and skipping modes are supported, as are

vertical and horizontal mirror operations.

• Frame Rate

AR0234CS is capable of running up to 120 fps at full

(1920 x 1200) resolution and 120 fps at 720p resolution

for MIPI interface.

• Embedded Data and Statistics

The AR0234CS has the capability to output image data

and statistics embedded within the frame timing.

• Multi−Camera Synchronization

The AR0234CS supports advanced line synchronization

controls for multi−camera (stereo) support.

• Context Switching and Register Updates Context

switching may be used to rapidly switch between two

sets of register values.

• Gain

A programmable analog gain of 1x to 16x applied

globally to all color channels is available along with

a digital gain of 1x to 16x that may be configured on

a per color channel basis.

• Automatic Exposure Control

The integrated automatic exposure control may be used

to ensure optimal settings of exposure and gain are

computed and updated every other frame.

• MIPI

The AR0234CS Global Shutter image sensor supports

one, two and four lanes of MIPI data. Compliant to

MIPI standards:

♦ MIPI Alliance Standard for CSI−2 version 1.2

♦ MIPI Alliance Standard for D−PHY version 1.0

• PLL

An on chip PLL provides reference clock flexibility and
