High-Speed USB 2.0 Video Camera Controller
1.
INTRODUCTION
1.1
General Description
The SQ930C High-Speed USB 2.0 Video Camera Controller is a highly integrated and cost-effective
solution designed for USB 2.0 PC Camera based applications. It can interface to major brands of CMOS
sensors with VGA / 1.3M pixels.
The SQ930C is designed for USB 2.0, the mainstream specification of personal computers. Without the
restrictions of USB 1.1 PC camera on USB band width, the SQ930C controller fully expresses the
advantage of USB 2.0 on band width (about 40X times faster than USB 1.1). It is also fully compliant with
USB 1.1 specification. The SQ930C utilizes lossless compression to achieve the best image quality.
With an embedded high-efficient JPEG encoder engine; the transmission rate can achieve 30 frames per
second at VGA raw data mode. Based on SQ years of experiences in image processing technology, the
SQ930C will be the best solution for PC camera manufacturers.
