AR0238: 1/2.7-Inch
2.1 Mp/Full HD Digital
Image Sensor
General Description
ON Semiconductor’s AR0238 is a 1/2.7-inch CMOS digital image
sensor with an activepixel array of 1928Hx1088V. It captures images
in either linear or high dynamic range modes, with a rollingshutter
readout. It includes sophisticated camera functions such as inpixel
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 twowire serial
interface. The AR0238 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.

GENERAL DESCRIPTION
The ON Semiconductor AR0238 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) through the
HiSPi port. In linear mode, it outputs 12bit or 10bit
ALaw compressed raw data, using the parallel or serial
(HiSPi) output port. In high dynamic range mode, it outputs
two exposure values that the ISP will combine into an HDR
image. 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 AR0238 includes additional features to allow
applicationspecific tuning: windowing and offset, auto
black level correction, and onboard temperature sensor.
Optional register information and histogram statistic
information can be embedded in the first and last 2 lines of
the image frame.
The AR0238 is designed to operate over a wide
temperature range of 30°C to +85°C ambient.
FUNCTIONAL OVERVIEW
The AR0238 is a progressivescan sensor that generates
a stream of pixel data at a constant frame rate. It uses an
onchip, phaselocked loop (PLL) that can be optionally
enabled to generate all internal clocks from a single master
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
configured in linear mode, and in HDR mode.
