2.4.5
Other Input Clocks
For information on the input clocks of other functional blocks of the platform such as SerDes see the specific section of this
document.
2.5
RESET Initialization
Table 12 describes the AC electrical specifications for the RESET initialization timing requirements of the MPC8610.
Table 13 provides the PLL lock times.
2.6
DDR and DDR2 SDRAM
This section describes the DC and AC electrical specifications for the DDR SDRAM interface of the MPC8610. Note that DDR
SDRAM is GVDD = 2.5 V and DDR2 SDRAM is GVDD = 1.8 V.
