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.
