See Standard Frequencies and Ordering Information for more information. 3. Includes calibration tolerance, operating temperature, supply voltage variations, aging and IR reflow. 4. Figure 1 defines the test circuit and Figure 2 defines these parameters. 5. Duty Cycle is defined as the On/Time Period. 6. Measured using an Agilent E5052, 155.520MHz. Please see Typical Phase Noise and Jitter Report for the VCC6 series. 7. Measured using a Wavecrest SIA3300C, 90K samples. 8. Outputs will be Enabled if Enable/Disable is left open. t t R F V -1.3V DD V OH 1 6 50% NC 2 5 V OL NC On Time 3 4 50 50 -1.3V Period Figure 1. Figure 2.
