Overview
Slow Clock RC Oscillator
Main Oscillator
Main Oscillator Connections
The Clock Generator is made up of 1 PLL, a Main Oscillator, as well as an RC Oscillator.
It provides the following clocks:
The Clock Generator User Interface is embedded within the Power Management Controller one
and is described in
The user has to take into account the possible drifts of the RC Oscillator. More details are given
in the section “DC Characteristics” of the product datasheet.
Figure 24-1
Figure 24-1. Main Oscillator Block Diagram
The Clock Generator integrates a Main Oscillator that is designed for a 3 to 20 MHz fundamental
crystal. The typical crystal connection is illustrated in
trical characteristics of the Main Oscillator, see the section “DC Characteristics” of the product
datasheet.
• SLCK, the Slow Clock, which is the only permanent clock within the system
• MAINCK is the output of the Main Oscillator
• PLLCK is the output of the Divider and PLL block
shows the Main Oscillator block diagram.
