‘SpreadTrak’
Many systems being designed now utilize a technology
called Spread Spectrum Frequency Timing Generation.
ASM5P23S04A is designed so as not to filter off the
Spread Spectrum feature of the Reference Input,
assuming it exists. When a zero delay buffer is not
designed to pass the Spread Spectrum feature through,
the result is a significant amount of tracking skew which
may
cause
problems
in
synchronization.
