6 Output PLL Frequency Generator
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 components.
Since the CDC5806 is based on PLL circuitry, it requires a stabilization time to achieve phase-lock of the PLLs The PLL stabilization time begins after the reference Clock input has a stable phase and frequency.
The device operates from a single 3.3-V supply voltage. The CDC5806 device is characterized for operation from ?40C to 85C.
