Note 2:
Some frequencies may be generated using two different values of specified performance from –40°C to 85°C. RSET. For these frequencies, the error is specified assuming that the larger

Consult the Applications Information section for operation with value of RSET is used. supplies higher than 3.6V.
Note 3:
Frequency accuracy is defined as the deviation from the fOUT
Note 9:
Long term drift on silicon oscillators is primarily due to the equation. movement of ions and impurities within the silicon and is tested at 30°C
Note 4:
Jitter is the ratio of the peak-to-peak deviation of the period to the under otherwise nominal operating conditions. Long term drift is specified mean of the period. This specification is based on characterization and is as ppm/√kHr due to the typically non-linear nature of the drift. To calculate not 100% tested. drift for a set time period, translate that time into thousands of hours, take
Note 5:
Current into a pin is given as a positive value. Current out of a pin the square root and multiply by the typical drift number. For instance, a is given as a negative value. year is 8.77kHr and would yield a drift of 888ppm at 300ppm/√kHr. Ten years is 87.7kHr and would yield a drift of 2,809 ppm at 300 ppm/√kHr.
Note 6:
Output rise and fall times are measured between the 10% and Drift without power applied to the device may be approximated as 1/10th of 90% power supply levels. the drift with power, or 30ppm/√kHr for a 300ppm/√kHr device. 6907fa 3
