3ch Clock Generators for Digital Cameras - BU2394KN

These clock generators are an IC generating three types of clocks–CCD, USB, and VIDEO clocks–necessary for digital still camera systems and digital video camera systems, with a single chip through making use of the PLL technology. Generating these clocks with a single chip allows for the simplification of clock system, little space occupancy, reduction in the number of components used for mobile camera equipment, which is becoming increasingly downsized and less costly.
