OV7949 - OmniVision

OV7949 NTSC/PAL product brief
high-performance automotive CameraChip™ sensor
available in
a lead-free
package
The newly enhanced OV7949 advanced CMOS
CameraChip sensor is designed specifically for
automotive imaging applications for driver assistance
and safety systems. The 1/3 inch, highly integrated
OV7949 video camera packs a high level of functionality
with a brand new design specifically engineered to excel
in low light conditions (<0.01 lux) and operate within a
wide temperature range from -40° to +85°C, which is
critical for automotive use. Combined with its
significantly reduced blooming and smearing effects,
the OV7949 can easily compete with more expensive
CCD solutions.
In the fast growing market for automotive cameras, the
OV7949 image sensor is the most cost efficient
high-performance solution for applications requiring a
color video camera with a small footprint, low voltage,
low power consumption and excellent low-light
performance.
The OV7949 supports NTSC/PAL composite video
output and can directly interface with an in-car LCD
screen or other device with 75 Ohm loading.
The OV7949 has completed all required AEC-Q100
Grade 2 qualifications.
