General Description
The ON Semiconductor MT9M034 is a 1/3-inch CMOS
digital image sensor with an active-pixel array of
1280H x 960V. It captures images in either linear or
high dynamic range modes, with a rolling-shutter
readout. It includes sophisticated camera functions
such as auto exposure control, 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
interface. The MT9M034 produces extraordinarily
clear, sharp digital pictures, and its ability to capture
both continuous video and single frames makes it the
perfect choice for a wide range of applications, includ-
ing surveillance and HD video.

Functional Overview

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
high dynamic range mode of operation where multiple images are combined on-chip to
produce a single image at 20-bit per pixel value. A compressing mode is further offered
to allow this 20-bit pixel value to be transmitted to the host system as a 12-bit value with
close to zero loss in image quality. The pixel data are output at a rate of up to 74.25 Mp/s,
in parallel to frame and line synchronization signals.

Notes:
1. All power supplies must be adequately decoupled.
2. ON Semiconductor recommends a resistor value of 1.5k, but a greater value may be used for
slower two-wire speed.
3. This pull-up resistor is not required if the controller drives a valid logic level on SCLK at all times.
4. ON Semiconductor recommends that 0.1μF and 10μF decoupling capacitors for each power supply
are mounted as close as possible to the pad. Actual values and results may vary depending on lay-

Digital Gain Control
MT9M034 supports four digital gains for the color channels: Red, Green1 (green pixels
on the red rows), Green2 (green pixels on the blue rows), and Blue. Digital gain control of
the MT9M034 is dependent on the configuration of the x_addr_start register. Table 4
illustrates how the digital gains are applied when x_addr_start is even or odd number.
