Notes: 1. Typical parameters represent the statistical mean values
2. See test circuit
3. Values can be selected in 1 pF steps. A total capacitance (COSCIN + COSCOUT) of 38 pF is available
4. These values are valid for 10 pF quartz applications. For CL = 12.5 pF these values change to 4.5, 6, 7.5, 9 pF
