General Description
ON Semiconductor's AR0230CS is a 1/2.7-inch CMOS
digital image sensor with an active-pixel array of
1928Hx1088V. 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 inter-
face. The AR0230CS produces extraordinarily clear,
sharp digital pictures, and its ability to capture both
continuous video and single frames makes it the per-
fect choice for a wide range of applications, including
surveillance and HD video.

AR0230CS: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor
Functional Overview
Functional Overview
The AR0230CS 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.

User interaction with the sensor is through the two-wire serial bus, which communi-
cates with the array control, analog signal chain, and digital signal chain. The core of the
sensor is a 2.1 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

Pixel Array Structure
While the sensor's format is 1928 x1088, additional active columns and active rows are
included for use when horizontal or vertical mirrored readout is enabled, to allow
readout to start on the same pixel. The pixel adjustment is always performed for mono-
chrome or color versions. The active area is surrounded with optically transparent
dummy pixels to improve image uniformity within the active area. Not all dummy pixels
or barrier pixels can be read out.
