Conditions

Note 1: The VC-830 power supply should be filtered. For example, a 10 µF, 0.1 µF, and 0.01 µF capacitor.

2: Includes calibration tolerance, operating temperature, supply voltage variations, aging, and IR reflow.

4: Output rise and fall time will be 600 ps (max.) for –40°C to +105°C operating temperature range.

5: Duty Cycle is measured as On/Time Period.

6: Measured using an Agilent E5052 Signal Source Analyzer at 25°C.

7: Outputs will be enabled if Enable/Disable is left open. There is an oscillation detection circuit that ensures

glitch free output upon power-up or enable.
