Allowable Temperature Drift for Continuous Lock is how far the temperature can drift in either direction and stay in lock from the ambient

temperature and programmed state at which the device was when the frequency calibration routine was run. The action of programming

the R15 register, even to the same value, when 0_DELAY_MODE = 0 activates a frequency calibration routine. This implies that the

device will work over the entire frequency range, but if the temperature drifts more than the maximum allowable drift for continuous lock,

then it will be necessary to reprogram the R15 register while 0_DELAY_MODE = 0 to ensure that the device stays in lock. Regardless of

what temperature the device was initially programmed at, the ambient temperature can never drift outside the range of -40 °C

°C without violating specifications. For this specification to be valid, the programmed state of the device must not change after R15 is

programmed except for 0_DELAY_MODE and PLL_N for the purpose of enabling 0-delay mode.

(8)

Output power varies as a function of frequency. When a range is shown, the higher output power applies to the lower frequency and the

lower output power applies to the higher frequency.

(9)

The lower sensitivity indicates the typical sensitivity at the lower end of the tuning range, the higher sensitivity at the higher end of the

tuning range

(10) Specification is guaranteed by characterization and is not tested in production.
