Low-Cost, 308MHz, 315MHz, and 433.92MHz
FSK Transceiver with Fractional-N PLL
AC ELECTRICAL CHARACTERISTICS (continued)
(Typical Application Circuit, 50Ω system impedance, VPAVDD = VAVDD = VDVDD = VHVIN = +2.1V to +3.6V, fRF = 308MHz, 315MHz. or
433.92MHz, TA = -40°C to +125°C, unless otherwise noted. Typical values are at VPAVDD = VAVDD = VDVDD = VHVIN = +2.7V,
TA = +25°C, unless otherwise noted.) (Note 1)
