Your complex system-on-a-chip may have just one or two clocks,
or it may have a dozen. In most systems, every one of these clocks
is derived from one or more phase-locked loops. Timing jitter from
these PLLs shows up on every timing path in your design, and in
every AC spec you promise to your customers. You owe your customers
and your engineers the finest PLLs available.
