NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.

PARAMETERS
Following Conditions Apply Unless Otherwise Specified:
Operating Condition: TA = 0°C to +70°C, Supply Voltage: VDD = 3.3V ± 5%
NOTES:
1. Input frequency should be measured at the REF output pin and tuned to ideal 14.31818MHz to meet ppm frequency accuracy on PLL outputs.
2. This parameter is guaranteed by design, but not 100% production tested.
3. See TIMING DIAGRAMS for timing requirements.
