Notes:
1. Positive slope; selectable option by part number. See Section 3. "Ordering Information" on page 8.
2. For best jitter and phase noise performance, always choose the smallest KV that meets the application’s minimum APR
requirements. See “AN266: VCXO Tuning Slope (KV), Stability, and Absolute Pull Range (APR)” for more information.
3. KV variation is ±10% of typical values.
4. BSL determined from deviation from best straight line fit with VC ranging from 10 to 90% of VDD. Incremental slope
determined with VC ranging from 10 to 90% of VDD.
