Notes:
1. Positive slope; selectable option by part number. See Section 3. "Ordering Information" on page 10.
2. For best jitter and phase noise performance, always choose the smallest K V that meets the application’s minimum APR
requirements. See “AN266: VCXO Tuning Slope (K V ), Stability, and Absolute Pull Range (APR)” for more information.
3. K V variation is ±10% of typical values.
4. BSL determined from deviation from best straight line fit with V C ranging from 10 to 90% of V DD . Incremental slope
determined with V C ranging from 10 to 90% of V DD .
