11 Bus Signal Timing
The maximum bus speed supported by the MPC875/MPC870 is 80 MHz. Higher-speed parts must be
operated in half-speed bus mode (for example, an MPC875/MPC870 used at 133 MHz must be configured
for a 66 MHz bus).

shows the frequency ranges for standard part frequencies in 2:1 bus mode.
Bus period (CLKOUT), see
EXTCLK to CLKOUT phase skew—If
CLKOUT is an integer multiple of EXTCLK,
then the rising edge of EXTCLK is aligned with
the rising edge of CLKOUT. For a non-integer
multiple of EXTCLK, this synchronization is
lost, and the rising edges of EXTCLK and
CLKOUT have a continuously varying phase
skew.
