MPC8245 Integrated Processor Hardware Specications
PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
Electrical and Thermal Characteristics
1.4.3.1 Clock AC Specications
Table 8 provides the clock AC timing specications as dened in Section 1.4.3.2, “Input AC Timing
Notes:
1
These specications are for the default driver strengths indicated in Table 4.
2
Rise and fall times for the PCI_SYNC_IN input are measured from 0.4 to 2.4 V.
3
Specication value at maximum frequency of operation.
4
Relock time is guaranteed by design and characterization. Relock time is not tested.
5
Rise and fall times for the OSC_IN input is guaranteed by design and characterization. OSC_IN input rise
and fall times are not tested.
6
Relock timing is guaranteed by design. PLL-relock time is the maximum amount of time required for PLL
lock after a stable Vdd and PCI_SYNC_IN are reached during the reset sequence. This specication also
applies when the PLL has been disabled and subsequently re-enabled during sleep mode. Also note that
HRST_CPU / HRST_CTRL must be held asserted for a minimum of 255 bus clocks after the PLL-relock
time during the reset sequence.
7
DLL_EXTEND is bit 7 of the PMC2 register <72>. N is a non-zero integer (1 or 2). Tclk is the period of
one SDRAM_SYNC_OUT clock cycle in ns. tloop is the propagation delay of the DLL synchronization
feedback loop (PC board runner) from SDRAM_SYNC_OUT to SDRAM_SYNC_IN in ns; 6.25 inches of
loop length (unloaded PC board runner) corresponds to approximately 1 ns of delay. tx0 is a xed delay
inherent in the design when the DLL is at tap point 0 and the DLL is contributing no delay; tx0 equals
approximately 3 ns. See Figure 5 through Figure 8 for DLL locking ranges.
