MOTOROLA
Electrical and Thermal Characteristics
Table 9 shows the values of Tdp(max) and Tdp(min)
Figure 7 through Figure 10 show the DLL locking range loop delay vs. frequency of operation. These
graphs define the areas of DLL locking for various modes. The grey areas represent areas where the DLL
will lock.
Note also that the DLL_MAX_DELAY bit can lengthen the amount of time through the delay line. This is
accomplished by increasing the time between each of the 128 tap points in the delay line. Although this
increased time makes it easier to guarantee that the reference clock will be within the DLL lock range, it
also means there may be slightly more jitter in the output clock of the DLL, should the phase comparator
shift the clock between adjacent tap points. Refer to the Motorola application note AN2164,
MPC8245/MPC8241 Memory Clock Design Guidelines, for details on memory design.
