Preliminary Datasheet
OV7949/OV7449 CMOS NTSC/PAL CAMERACHIPTM Sensor
with OmniPixel® Technology for Automotive Applications
General Description
The OV7949 (color) and OV7449 (B&W) single chip
CMOS CAMERACHIP™ image sensors are designed to
provide a high level of functionality for applications
requiring a small footprint, low voltage, low power
consumption and high performance color video camera.
The OV7949 supports NTSC/PAL composite video output
and can directly interface with a VCR TV monitor or other
device with 75 ohm loading.
Note: The OV7949 is available in a
Pb lead-free package.
Features
• Single chip 1/3" format video camera
• Composite video (NTSC/PAL) differential output
drive
• Sensitivity boost (+42 dB)
• Automatic exposure/gain with 16 zone control
• Auto white balance control
• Aperture/Gamma correction
• 50/60 Hz flicker cancellation
• External frame sync capability
• SPI/EEPROM used to control overlay and set other
customer variables
• I2C compatible Serial Camera Control Bus (SCCB)
control interface for register programming
• Low power consumption
• Extremely low dark current for high temperature
applications
• Defective pixel correction
• Genlock
• QFP parts qualified to AEC-Q100 standard
