FREESCALE SEMICONDUCTOR ADVANCED CLOCK DRIVERS DEVICE DATA
Where Rthja is the thermal impedance of the package
(junction to ambient) and TA is the ambient temperature.
According to Table 9.Die Junction Temperature and MTBF, 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.
TJ,MAX should be selected according to the MTBF system
requirements and Table 9.Die Junction Temperature and MTBF.
on 1S2P boards, using 2S2P boards will result in a lower
thermal impedance than indicated below.
If the calculated maximum frequency is below 200 MHz, it
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.
