becomes the upper clock speed limit for the given application
conditions. The following eight derating charts describe the
safe frequency operation range for the MPC9448. The charts
were calculated for a maximum tolerable die junction
temperature of 110°C (120°C), corresponding to an
estimated MTBF of 9.1 years (4 years), a supply voltage of
3.3 V and series terminated transmission line or capacitive
loading. Depending on a given set of these operating
conditions and the available device convection, a decision on
the maximum operating frequency can be made.
