1. Low power mode requires reprogramming of the device reference current (REF_I) as well as the synthesizer VCO current (VCO_I) and there
are trade−offs with the lowest achievable power supply value as well as with sensitivity. Sensitivities and operating conditions in this
data−sheet do not refer to low power mode.
