RESET Initialization
This section describes the AC electrical specifications for the RESET initialization timing requirements of
the MPC8548E. Table 8 provides the RESET initialization AC timing specifications for the DDR SDRAM
component(s).
Table 9 provides the PLL lock times.
5.1
Power-On Ramp Rate
This section describes the AC electrical specifications for the power-on ramp rate requirements. Table 10
provides the power supply ramp rate specifications.

Note:
1. Ramp rate is specified as a linear ramp. If non-linear (e.g. exponential), ramp rate from near zero to 400 mV is most critical
as this range might falsely trigger the ESD circuitry.
