Notes:
1. Selectable parameter specified by part number. See 3. "Ordering Information" on page 7 for further details.
2. FS pin includes an internal 17 kï pullup resistor to VDD. When the FS is left floating, the pullup causes
FS = 1 = second frequency selected.

Notes:
1. Positive slope; selectable option by part number. See 3. "Ordering Information" on page 7.
2. For best jitter and phase noise performance, always choose the smallest KV that meets the applicationâs minimum APR
requirements. See âAN266: VCXO Tuning Slope (KV), Stability, and Absolute Pull Range (APR)â 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.
