CDC5806 Datasheet (Texas Instruments) - THREE PLLs BASED CLOCK GENERATOR

CDC5806, THREE PLLs BASED CLOCK 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.
