Notes:
1. Selectable parameter specified by part number. See Section 3. "Ordering Information" on page 7 for further details.
2. OE and FS[1:0] pins include a 17 k
pullup resistor to VDD. Pulling OE to ground causes outputs to tristate.
3. If the device is powered up below –20 C and the ambient temperature rises by approximately 105 C during normal
operation, the device will perform a one-time recalibration. The output is squelched for approximately 2–3 ms during
this recalibration.

Notes:
1. Positive slope; selectable option by part number. See Section 3. "Ordering Information" on page 7.
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 ±28% 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.
