Phase-locked loop (PLL) clock generator

Using a 54-MHz system clock, the CDC5806 clock generator is able to bring together audio and video clocks along with a USB clock, CPU clock, ASIC clock and memory card clock.

The system clock produces multiple frequencies with the help of three phase-locked loops or PLLs. Extraneous components are rendered redundant thanks to loop filters on the chip and internal feedback.

Being built on PLL circuitry, stabilization time is essential on the CDC5806 for it to have the phase-lock characteristic of PLLs. Of course, this stabilization time commences only after the reference clock has entered the stage of stability in frequency and phase.

There is a solitary 3.3-V source of power. It works best between ?40°C to 85°C temperatures.
