1 _{TJavg does not exceed 85°C in a typical temperature profile over the lifetime of a consumer, industrial or automotive application.}
2 _{Typical data retention values are based on intrinsic capability of the technology measured at high temperature and de-rated to}
25°C using the Arrhenius equation. For additional information on how Freescale defines Typical Data Retention, please refer to

A.8 Phase Locked Loop
A.8.1 Jitter Definitions
With each transition of the feedback clock, the deviation from the reference clock is measured and input
voltage to the VCO is adjusted accordingly.The adjustment is done continuously with no abrupt changes
in the VCOCLK frequency. Noise, voltage, temperature and other factors cause slight variations in the
control loop resulting in a clock jitter. This jitter affects the real minimum and maximum clock periods as
illustrated in Figure A-4.
