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
