SECTION 1

PRODUCT OVERVIEW

OV7620 is a highly integrated high resolution (640x480) Interlaced / Progressive Scan CMOS

digital color / black&white video camera chip. The digital video port supports 60Hz YCrCb 4:2:2

16Bit / 8 Bit format, ZV Port output format, RGB raw data 16Bit/8Bit output format and CCIR601/

CCIR656 format. The built-in SCCB (Serial Camera Control Bus) interface provides an easy way

of controlling the built-in camera functions.
