General Description
The ON Semiconductor MT9D131 is a 1/3.2 inch, 2 Mp CMOS
image sensor with an integrated advanced camera system. The camera
system features a microcontroller (MCU) and a sophisticated image
flow processor (IFP) with a real-time JPEG encoder.
The microcontroller manages all components of the camera system
and sets key operation parameters for the sensor core to optimize the
quality of raw image data entering the IFP. The sensor core consists of
an active pixel array of 1668 x 1248 pixels, programmable timing and
control circuitry including a PLL, analog signal chain with automatic
offset correction and programmable gain, and two 10-bit A/D
converters (ADC). The entire system-on-a-chip (SOC) has ultra-low
power requirements and superior low-light performance that is
particularly suitable for surveillance applications.

this data sheet.
The excellent low-light performance of MT9D131 is one of the
hallmarks of ON Semiconductor’s breakthrough low-noise CMOS
imaging technology that achieves CCD image quality (based on
signal-to-noise ratio and low-light sensitivity) while maintaining the
inherent size, cost, power consumption, and integration advantages of
CMOS.

Feature Overview
The MT9D131 is a color image sensor with a Bayer color filter
arrangement. Its basic characteristics are described in Table 1.
The MT9D131 has an embedded phase-locked loop oscillator (PLL)
that can be used with the common wireless system clock. When in use,
the PLL adjusts the incoming clock frequency, allowing the MT9D131
to run at almost any desired resolution and frame rate. To reduce
power consumption, the PLL can be bypassed and powered down.
Low power consumption is a very important requirement for all
components of wireless devices. The MT9D131 has numerous power
conserving features, including an ultra low-power standby mode and
the ability to individually shut down unused digital blocks.
Another important consideration for wireless devices is their
electromagnetic emission or interference (EMI). The MT9D131 has a
programmable I/O slew rate to minimize its EMI and an output FIFO
to eliminate output data bursts.
The advanced IFP and flexible programmability of the MT9D131
provide a variety of ways to enhance and optimize the image sensor
performance. Built-in optimization algorithms enable the MT9D131
to operate at factory settings as a fully automatic, highly adaptable
camera. However, most of its settings are user-programmable.
Applications
• Network Security Cameras
• ePTZ Cameras
• Output FIFO for Data Rate Equalization
• Programmable I/O Slew Rate
