FIGURE 1 USB PC CAMERA SYSTEM BLOCK DIAGRAM
The ZC0302 chip provides a cost effective single chip solution for the PC camera application. It communicates with
PC host via Universal Serial Bus (USB) port. All major image processing functions, such as image signal
processing (ISP), image data compression and data transfer units are built in the chip. Meanwhile ZC0302 also
provides high quality audio sampling function for sound recording. The audio function complies with USB audio class
1.0.
ZC0302 is designed as a cost-effective single-chip device replacing the complex and costly chip sets used in current
PC camera designs with embedded USB device controller and transceiver, 48-QFP package, and no external
DRAM requirement. Advanced on-chip image signal processor and JPEG encoder produce images with superior
quality.
