the junction temperature can be used to estimate the long-term
device reliability. Further, combining equation 1 and equation 2
results in a maximum operating frequency for the MPC961C in a
series terminated transmission line system.

becomes the upper clock speed limit for the given application
conditions. The following two derating charts describe the safe
frequency operation range for the MPC961C. The charts were
calculated for a maximum tolerable die junction temperature of
110°C, corresponding to an estimated MTBF of 9.1 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. There are no operating frequency
limitations if a 2.5 V power supply or the system specifications allow
for a MTBF of 4 years (corresponding to a max. junction temperature
of 120°C).
