Electrical and Thermal Characteristics
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 Motorola Application Note AN2164,
MPC8245/MPC8241 Memory Clock Design Guidelines, for more details on memory design.
