PAC207B SINGLE-CHIP CIF CMOS IMAGE SENSOR

WITH USB INTERFACE

1. GENERAL DESCRIPTION

The PAC207B is a single chip CMOS image sensor embedded with an USB 1.1 interface and image

compression function. The PAC207B is suitable for low-cost high performance PC camera

applications. It integrates on-chip power regulators to transfer the 5V voltage from USB host power to

proper voltage levels to supply the CMOS sensor and analog and digital circuitry. Hence there is no

need to have external power regulator on the PCB. All the image processing functions, interpolation,

auto exposure, auto white balance, de-flickering and sharpness, are performed by software in PC side.

The optical size is 1/7”, which can easily be embedded into LCD monitors, notebooks or PDA.
