AR0542: 1/4-Inch CMOS Digital Image Sensor
General Description
General Description
The AR0542 digital image sensor features ON Semiconductor’s breakthrough low-noise
CMOS imaging technology that achieves near-CCD image quality (based on signal-to-
noise ratio and low-light sensitivity) while maintaining the inherent size, cost, and inte-
gration advantages of CMOS.
The AR0542 sensor can generate full resolution image at up to 15 frames per second
(fps). An on-chip analog-to-digital converter (ADC) generates a 10-bit value for each
pixel.
Functional Overview
The AR0542 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) to generate all internal
clocks from a single master input clock running between 6 and 27 MHz. The maximum
pixel rate is 84 Mp/s, corresponding to a pixel clock rate of 84 MHz. A block diagram of
the sensor is shown in Figure 1.

Interface
The core of the sensor is a 5Mp active-pixel 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 inte-
grate 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 are sequenced
through an analog signal chain (providing offset correction and gain), and then through
an 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 array contains optically active and light-shielded (“dark”) pixels. The dark
pixels are used to provide data for on-chip offset-correction algorithms (“black level”
control).
The sensor contains a set of control and status registers that can be used to control many
aspects of the sensor behavior including the frame size, exposure, and gain setting.
These registers can be accessed through a two-wire serial interface.
