ASK/FSK Transceiver with Fractional-N PLL

DC ELECTRICAL CHARACTERISTICS (continued)

(Typical Application Circuit, 50Ω system impedance, VAVDD = VDVDD = VPAVDD = VHVIN = +2.1V to +3.6V, fRF = 300MHz to 450MHz,

TA = -40°C to +125°C, unless otherwise noted. Typical values are at VAVDD = VDVDD = VPAVDD = VHVIN = +2.7V, TA = +25°C, unless

otherwise noted.) (Note 1)
