Notes:
1. Pin 4 VDD should be filtered with 0.1uF capacitor.
2. Output is enabled if OE pad is high or not connected. Supply current = Disabled Current + IDD from CLK0 + IDD from CLK1. See Current
Consumption graph on next page.
3. tSU is time to stable output frequency after VDD is applied and outputs are enabled.
4. See Figure 3 for detail (all based on maximum drive settings).
5. Period Jitter includes crosstalk from adjacent output.
6. For other ppm stabilities, contact the factory at MEMS_Support@micrel.com.
