Note 6:
Output rise and fall times are measured between the 10% and 90% section). For these frequencies, the error is specified under the following power supply levels. These specifications are based on characterization. assumption: 10k < RSET ≤ 100k. The frequency accuracy for fOSC = 20MHz
Note 7:
