General Description
The ON Semiconductor AR0542 is a 1/4-inch CMOS
active-pixel digital image sensor with a pixel array of
2592H x 1944V (2608H x 1960V including border pix-
els). It incorporates sophisticated on-chip camera
functions such as windowing, mirroring, column and
row skip modes, and snapshot mode. It is programma-
ble through a simple two-wire serial interface and has
very low power consumption.

AR0542: 1/4-Inch CMOS Digital Image Sensor
Functional Overview
The output from the sensor is a Bayer pattern; alternate rows are a sequence of either
green and red pixels or blue and green pixels. The offset and gain stages of the analog
signal chain provide per-color control of the pixel data.
The control registers, timing and control, and digital processing functions shown in
Figure 1 on page 6 are partitioned into three logical parts:
• A sensor core that provides array control and data path corrections. The output of the
sensor core is a 10-bit parallel pixel data stream qualified by an output data clock
(PIXCLK), together with LINE_VALID (LV) and FRAME_VALID (FV) signals.
• A digital shading correction block to compensate for color/brightness shading intro-
duced by the lens or chief ray angle (CRA) curve mismatch.
• Additional functionality is provided. This includes a horizontal and vertical image
scaler, a limiter, a data compressor, an output FIFO, and a serializer.
The output FIFO is present to prevent data bursts by keeping the data rate continuous.
Programmable slew rates are also available to reduce the effect of electromagnetic inter-
ference from the output interface.
A flash output signal is provided to allow an external Xenon or LED light source to
synchronize with the sensor exposure time.
Pixel Array
The sensor core uses a Bayer color pattern, as shown in Figure 2. The even-numbered
rows contain green and red pixels; odd-numbered rows contain blue and green pixels.
Even-numbered columns contain green and blue pixels; odd-numbered columns
contain red and green pixels.
