4. Block Diagram
PAC7301/PAC7302 is a USB PC Camera SOC with enhanced image quality and sensitivity, internal regulators,
JPEG image compression, image processing schemed, control registers, on-chip SRAM for image data buffer and
USB controller. All register parameters are set by USB interface. And the JPEG compressed image data is
transmitted by USB 1.1 isochronous pipe.
