Oscillator and PLLMRFM Electrical
Characteristics
5
Current measured at maximum system clock frequency, all modules active, and default drive strength with matching
load.
6
All functional non-supply pins are internally clamped to VSS and their respective VDD.
7
Input must be current limited to the value specified. To determine the value of the required current-limiting resistor,
calculate resistance values for positive and negative clamp voltages, then use the larger of the two values.
8
Power supply must maintain regulation within operating VDD range during instantaneous and operating maximum
current conditions. If positive injection current (Vin > VDD) is greater than IDD, the injection current may flow out of VDD
and could result in external power supply going out of regulation. Insure external VDD load will shunt current greater
than maximum injection current. This will be the greatest risk when the processor is not consuming power. Examples
are: if no system clock is present, or if clock rate is very low which would reduce overall power consumption. Also, at
power-up, system clock is not present during the power-up sequence until the PLL has attained lock.
