APPLICATIONS INFORMATION
Using the On–Board Crystal Oscillator
The MPC980 features an on–board crystal Oscillator to
allow for seed clock generation as well as final distribution.
The on–board Oscillator is completely self contained so that
the only external component required is the crystal. As the
Oscillator is somewhat sensitive to loading on its inputs the
user is advised to mount the crystal as close to the MPC980
as possible to avoid any board level parasitics. To facilitate
co–location surface mount crystals are recommended, but
not required.
The Oscillator circuit is a series resonant circuit as
opposed to the more common parallel resonant circuit, this
eliminates the need for large on–board capacitors. Because
the design is a series resonant design for the optimum
frequency accuracy a series resonant crystal should be used
(see specification table below). Unfortunately most off the
shelf crystals are characterized in a parallel resonant mode.
However a parallel resonant crystal is physically no different
than a series resonant crystal, a parallel resonant crystal is
simply a crystal which has been characterized in its parallel
