TC5747 Data Sheet
Single Chip CMOS Imager
1. Introduction
The TC5747 is a single chip VGA (640 lines over 480 pixels) color CMOS sensor with an integrated color
processing and JPEG codec. It is designed to meet the requirements of cellular devices with low power
consumption and miniature size. An embedded programmable core with dedicated hardware performs the
extensive color processing. An embedded real-time JPEG encoder and compressed frames SRAM store
JPEG images on chip. The TC5747 has flexible interfaces and supports multiple video output formats for
easy integration into cellular phones. It supports a 16-bit host interface for fast data access and control.
