Electrical and Thermal Characteristics
Freescale Semiconductor

The system PLL (SYS_PLL) takes an external reference frequency and generates the internal system clock. The
system clock frequency is determined by the external reference frequency and the settings of the SYS_PLL
configuration.
The e300 core PLL (CORE_PLL) generates a master clock for all of the CPU circuitry. The e300 core clock frequency
is determined by the system clock frequency and the settings of the CORE_PLL configuration.
4.2.1
System Oscillator Electrical Characteristics
The system oscillator can work in oscillator mode or in bypass mode to support an external input clock as clock reference.

NOTES:
1 The SYS_XTALI frequency and system PLL settings must be chosen such that the resulting system frequencies do not exceed
their respective maximum or minimum operating frequencies. See the MPC5125 Reference Manual (MPC5125RM).
2 The min/max cycle times are calculated using 1/f
sys_xtal (MIN/MAX) where the fsys_xtal (MIN/MAX) (15.6 / 35 MHz) are taken from
Table 12 (system oscillator electrical characteristics).
