Maximum Input Current
Load Capacitance determined from crystal manufacturer specifications and will include circuit board parasitics.
This specification applies to the period required for the PLL to relock after changing the MFD frequency control bits in the
synthesizer control register (SYNCR).
Assuming a reference is available at power up, lock time is measured from the time V
RSTO negating. If the crystal oscillator is being used as the reference for the PLL, then the crystal start up time
must be added to the PLL lock time to determine the total start-up time.
PLL is operating in 1:1 PLL mode.
Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f
Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal.

Refers to allowed random sequencing of power supplies.
Transitions within the limit do not affect device reliability or cause permanent damage. Exceeding limit may cause
permanent conversion error on stressed channels and on unstressed channels.
Input must be current limited to the value specified. To determine the value of the required current-limiting resistor,
calculate resistance values using V
calculated values.
Condition applies to one pin at a time.
