Test Conditions/Comments
As measured from completion of the VCO calibration
command (the rising edge of CS (Pin 12)) until the rising
edge of LOCKED (Pin 20).
Applies for A[3:0] = 0001 to 1100 or for A[3:0] = 1111.
Applies for A[3:0] = 1101 to 1110.
Using the pin selected frequency settings. Lock time is
from the rising edge of the RESET pin to the rising edge of
the LOCKED pin.
Applies for A[3:0] = 0001 to 1100 or for A[3:0] = 1111.
Applies for A[3:0] = 1101 to 1110.

MHz
When using the pin selected frequency settings, the device
requires a 25 MHz crystal to support holdover functionality.

pF
Using a crystal with a specified load capacitance other than 10 pF
(8 pF to 24 pF) is possible, but necessitates using the SPI port.
