PLL Configuration

PLL Configuration
The internal PLLs of the MPC8245 are configured by the PLL_CFG[0:4] signals. For a given
PCI_SYNC_IN (PCI bus) frequency, the PLL configuration signals set both the peripheral logic/memory
bus PLL (VCO) frequency of operation for the PCI-to-memory frequency multiplying and the MPC603e
CPU PLL (VCO) frequency of operation for memory-to-CPU frequency multiplying. The PLL

Notes:
1.
Place a pull-up resistor of 120
or less on the TEST0 pin.
2.
Treat these pins as no connects (NC) unless using debug address functionality.
3.
This pin has an internal pull-up resistor which is enabled only when the MPC8245 is in the reset state. The value
of the internal pull-up resistor is not guaranteed, but is sufficient to ensure that a logic 1 is read into configuration
bits during reset.
4.
This pin is a reset configuration pin.
5.
DL[0] is a reset configuration pin and has an internal pull-up resistor which is enabled only when the MPC8245 is
in the reset state. The value of the internal pull-up resistor is not guaranteed, but is sufficient to ensure that a logic 1
is read into configuration bits during reset.
6.
Multi-pin signals such as AD[31:0] or MDL[0:31] have their physical package pin numbers listed in order,
corresponding to the signal names. Example: AD0 is on pin C22, AD1 is on pin D22, ..., AD31 is on pin V25.
7.
GNT4 is a reset configuration pin and has an internal pull-up resistor which is enabled only when the MPC8245 is
in the reset state.
8.
Recommend a weak pull-up resistor (2–10 k
) be placed on this PCI control pin to LVDD.
9.
10. Recommend a weak pull-up resistor (2–10 k
) be placed on this pin to OVDD.
11. Recommend a weak pull-up resistor (2–10 k
) be placed on this pin to GVDD.
12. This pin has an internal pull-up resistor which is enabled at all times. The value of the internal pull-up resistor is
not guaranteed, but is sufficient to prevent unused inputs from floating.
13. External PCI clocking source or fan-out buffer may be required for system if using the MPC8245 DUART
functionality since PCI_CLK[0:3] are not available in DUART mode. Only PCI_CLK4 is available in DUART mode.
14. This pin is a multiplexed signal and appears more than once in this table.
15. This pin is affected by programmable PCI_HOLD_DEL parameter.
16. This pin is an open drain signal.
17. This pin can be programmed to be driven (default) or can be programmed (in PMCR2) to be open drain.
18. This pin is a sustained three-state pin as defined by the PCI Local Bus Specification.
19. OSC_IN utilizes the 3.3-V PCI interface driver which is 5-V tolerant, see Table 2 for details.
20. PLL_CFG[0:4] signals are sampled a few clocks after the negation of HRST_CPU and HRST_CTRL.
21. SDRAM_CLK[0:3] and SDRAM_SYNC_OUT signals use DRV_MEM_CTRL for chip Rev 1.1 (A). These signals
use DRV_MEM_CLK for chip Rev 1.2 (B).
22. The 266- and 300-MHz part offerings can be run at a source voltage of 1.8 ± 100 mV or 2.0 ± 100 mV. Note that
source voltage should be 2.0 ± 100 mV for 333- and 350-MHz parts.
23. This pin was formally LAVDD on the MPC8240. It is a no connect on the MPC8245. This should not pose a problem
when replacing an MPC8240 with an MPC8245.
24. The driver capability of this pin is hardwired to 40
and cannot be changed.
