2. Measured over 10K cycles. Jitter is only specified at the default high drive strength (50 output impedance).
3. Jitter is highly dependent on device frequency configuration. Specifications represent a "worst case, real world" frequency plan; actual performance may be substantially better. Three-output 10 MSOP package measured with clock outputs of 74.25, 24.576, and 48 MHz. Eight-output 20-QFN package measured with clock outputs of 33.333, 74.25, 27, 24.576, 22.5792, 28.322, 125, and 48 MHz.

Notes:
1. Crystals which require load capacitances of 6, 8, or 10 pF should use the device's internal load capacitance for optimum performance. See register 183 bits 7:6. A crystal with a 12 pF load capacitance requirement should use a combination of the internal 10 pF load capacitance in addition to external 2 pF load capacitance (e.g., by using 4 pF capacitors on XA and XB).
2. Refer to "AN551: Crystal Selection Guide" for more details.

Functional operation should be restricted to the conditions as specified in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
2. The device is compliant with JEDEC J-STD-020.

Recommended Operating Conditions
| Parameter | Symbol | Test Condition | Min | Typ | Max | Unit |
|---|---|---|---|---|---|---|
| Ambient Temperature | TA | –40 | 25 | 85 | °C | |
| Core Supply Voltage | VDD | 3.0 | 3.3 | 3.60 | V | |
| Core Supply Voltage | VDD | 2.25 | 2.5 | 2.75 | V | |
| Core Supply Voltage | VDD | 1.71 | 1.8 | 1.89 | V | |
| Output Buffer Voltage | VDDOx | 2.25 | 2.5 | 2.75 | V | |
| Output Buffer Voltage | VDDOx | 3.0 | 3.3 | 3.60 | V |
**Notes:**All minimum and maximum specifications are guaranteed and apply across the recommended operating conditions. Typical values apply at nominal supply voltages and an operating temperature of 25 °C unless otherwise noted. VDD and VDDOx can be operated at independent voltages.
Power supply sequencing for VDD and VDDOx requires that all VDDOx be powered up either before or at the same time as VDD.
