Low-Cost, 315MHz, 345MHz, and 433.92MHz
ASK Transceiver with Fractional-N PLL
DC ELECTRICAL CHARACTERISTICS (continued)
(Typical Application Circuit, 50⦠system impedance, VAVDD = VDVDD = VHVIN = VPAVDD = +2.1V to +3.6V, fRF = 315MHz, 345MHz, or
433.92MHz, TA = -40°C to +125°C, unless otherwise noted. Typical values are at VAVDD = VDVDD = VHVIN = VPAVDD = +2.7V,
TA = +25°C, unless otherwise noted.) (Note 1)
