    Clocking for the MPC8349E MDS Processor Board Clocking for the MPC8349E MDS Processor Board This chapter describes the clocking and timing of the MPC8349 while being used on the MPC8349E MDS Processor Board. Two primary clock sources are available for the MPC8349: CLKIN or PCICLK, depending on whether the device is a Host (that is, in Stand-Alone or PIB Combined Mode) or working in the Agent Mode (inserted in a PC compatible computer).

  • Page 52: Mpc8349 As Agent

    Clocking for the MPC8349E MDS Processor Board plugged into the PIB. CLKIN directly feeds the PCI_CLK output clocks dividers, and is also driven out on the PCI_SYNC_OUT pin for de-skewing of the external PCI_CLK clocks with the CLKIN signal. Since the PIB uses a programmable clock synthesizer, this clocking mode will be preferable for chip verification.
