1) The maximum limit is only relevant for PLL operation to ensure the minimum input frequency for the PLL.
2) The clock input signal must reach the defined levels
Figure 14
Note: If the on-chip oscillator is used together with a crystal or a ceramic resonator, the
Data Sheet
oscillator frequency is limited to a range of 4 MHz to 16 MHz.
It is strongly recommended to measure the oscillation allowance (negative
resistance) in the final target system (layout) to determine the optimum
parameters for the oscillator operation. Please refer to the limits specified by the
crystal supplier.
When driven by an external clock signal it will accept the specified frequency
range. Operation at lower input frequencies is possible but is verified by design
only (not subject to production test).
