1) a) When the minimum T_A is increased by 5°C, the minimum f_VCO decreases by 1 MHz.
b) When the maximum T_A is decreased by 5°C, the maximum f_VCO increases by 1 MHz.
c) When the minimum V_S is increased by 25 mV, the maximum f_VCO increases by 1 MHz.
Restriction of c): The maximum f_VCO must not be increased by more than 40 MHz by increasing V_S.
Please note that f_VCO is twice the Output Frequency.
All three measures can be taken independently and additive.
2) Derating linearly to a saturation voltage of max. 140 mV at I_CLKOUT = 0 mA
3) Matching circuitry as used in the 50 Ohm-Output Testboard.
Tolerances of the passive elements not taken into account.
Range @ 2.1 V, +25°C: 6.5 dBm +/- 2 dBm
Range @ 3.0 V, +25°C: 10 dBm +/- 3 dBm
Range @ 4.0 V, +25°C: 11.5 dBm +4.5/-3.5 dBm
