OmniVision OV2655 High sensitivity 1/5-inch 2 megapixel camerachip sensor Datasheet

OV2655 2 megapixel product brief
high sensitivity 1/5-inch 2 megapixel CameraChip™ sensor
available in
a lead-free
package
The OV2655 is a single-chip, high-performance
2 megapixel CMOS CameraChip sensor with a 1/5-inch
optical format. The OV2655 is based on OmniVision’s
1.75 micron OmniPixel3-HS™ architecture which uses
Ultra Low Stack Height (ULSH) pixels to acheive industryleading low-light sensitivity of 1030 mV/(Lux-sec), which
is vital for high frame rate video applications. The small
form factor of the OV2655 also makes it possible for it to
fit in a 6.5 x 6.5 mm camera module.
The OV2655 operates at up to 15 frames per second (fps)
in full resolution and 30 fps in SVGA mode. The captured
data can be transferred either by a standard parallel
digital video port (DVP) or by a single-lane MIPI
high-speed serial interface. The DVP can also be used for
input from an external secondary camera, enabling the
advanced ISP of the OV2655 to be used by the secondary
camera with continued output through the MIPI interface.
Despite its small form factor, the OV2655 has an
advanced image signal processor embedded with all
functions required by a high-performance camera.
For identification purposes, the OV2655 includes
one-time programmable (OTP) memory.
