Figure 2. Output Waveform

Figure 3. Output Test Conditions

(25 ±5°C)

1. A 0.1 µF low frequency tantalum bypass capacitor in parallel with a 0.01 µF high frequency ceramic capacitor is recommended.

2. Figure 2 defines the waveform parameters. Figure 3 illustrates the standard test conditions under which these parameters are

specified and tested.

3. Duty cycle is defined as (on time period), with VS = VDD/2, per Figure 2. Duty cycle is measured with a 15pf load per Figure 3.

4. Other frequencies may be available, please contact factory.
