RTC clock low time
PLL lock times
DLL lock times
Notes:
1. DLL lock times are a function of the ratio between the output clock and the platform (or CCB) clock. A 2:1 ratio results in the
2. The CCB clock is determined by the SYSCLK × platform PLL ratio.
Required assertion time of HRESET
Minimum assertion time for SRESET
PLL input setup time with stable SYSCLK before HRESET
negation
Input setup time for POR configs (other than PLL config) with
respect to negation of HRESET
Input hold time for POR configs (including PLL config) with
respect to negation of HRESET
Maximum valid-to-high impedance time for actively driven POR
configs with respect to negation of HRESET
Notes:
1. SYSCLK is identical to the PCI_CLK signal and is the primary clock input for the MPC8541E. See the MPC8555E
minimum and an 8:1 ratio results in the maximum.
