OSCin Sensitivity for Single-Ended SINE Wave
30073330
The above chart shows the typical sensitivity for a sine wave. Note that at lower frequencies, there is a constant slope that suggests that the part fails when the
slew rate falls below 27 V/us. The electrical specifications call for a minimum of 150 V/us to ensure margin. Also, as some of the other performance graphs show,
the OSCin slew rate has an impact on fractional spurs and phase noise as well. It is recommended to design to the electrical specifications, not the typical
performance plots.
Variation over voltage and temperature is typically very small and on the order than less ±1 dB.
SINE wave ExtVCOin Sensitivity
30073331
The above plot shows the ExtVCOin sensitivity which applies only when the device is being used in External VCO mode.
Variation over voltage is typically very small and on the order of less than ± 1 dB.
