The OV7930 (color) is a high performance quarter-inch
CMOS C
AMERA
C
HIPTM
designed for all applications
requiring a small footprint, low voltage, low power
consumption and low cost color video camera.
The device supports NTSC composite video output and
can directly interface with a VCR TV monitor or other
75 ohm terminated input with 2X standard TV signal
range. The OV7930 C
AMERA
C
HIP
s require only a single
5-volt DC power supply and have been designed for very
low power operation.
