Legend: TBD = To Be Determined.

These parameters are characterized but not tested.

† Data in the Typical (“Typ”) column is at 5V, 25

°C unless otherwise stated. These parameters are for design

guidance only and are not tested.

Note 1:

To ensure these oscillator frequency tolerances, VDD and VSS must be capacitively decoupled as close to

the device as possible. 0.1 uF and 0.01 uF values in parallel are recommended.

Note:

All tests must be done with specified capacitive loads (see data sheet) 50 pF on I/O pins and CLKOUT.
