CDC5806 Overview
The CDC5806 is a clock generator which synthesizes video clocks, audio clocks, CPU clock, ASIC clock, USB clock, and a memory card clock from a 54-MHz system clock. Three phase-locked loops (PLLs) are used to generate the different frequencies from the system clock. On-chip loop filters and internal feedback eliminate the need for external ponents.
