ELECTRICAL CHARACTERISTICS - 24_48MHZ, 48MHZ, USB
FollowingConditionsApplyUnlessOtherwiseSpecified:
Operating Condition: TA = 0°C to +70°C, Supply Voltage: VDD = 3.3V ± 5%; CL = 10 - 20pF
NOTES:
1. This parameter is guaranteed by design, but not 100% production tested.
2. All long term accuracy and clock period specifications are guaranteed with the assumption that the REF output is at 14.31818MHz.
