General Description
ON Semiconductor's AR0237 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 AR0237 produces extraordinarily clear, sharp
digital pictures, and its ability to capture both continu-
ous video and single frames makes it the perfect choice
for a wide range of applications, including surveillance
and HD video.

AR0237CS: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor
Functional Overview
Functional Overview
The AR0237 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
