Preliminary Data Sheet
440GR – PPC440GR Embedded Processor
Example 1:
If the data-to-PLB clock timing is as shown in the example below, then the read clock is not delayed and the Stage
1 data is sampled at (1). Except for small, low frequency memory systems with the memory located physically close
to the PPC440GR, it is unlikely that Stage 1 data can be sampled. When the data comes later, it is necessary to
sample Stage 2 or Stage 3 data. (see Examples 2 and 3). Another way to get the desired data-to-PLB timing to
allow Stage 1 sampling is to buffer MemClkOut0 and skew it enough to guarantee the timing. In this example, TT is
controlled and set by the software.
