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 12−bit or 10−bit

A−Law 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

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 AR0238 is designed to operate over a wide

temperature range of −30

°C to +85°C junction.

FUNCTIONAL OVERVIEW

The AR0238 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 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.
