Maxim Integrated 

Low-Cost, 315MHz, 345MHz, and 433.92MHz

ASK Transceiver with Fractional-N PLL

DC ELECTRICAL CHARACTERISTICS (continued)

(Typical Application Circuit, 50Ω system impedance, AVDD = DVDD = HVIN = PAVDD = +2.1V to +3.6V, fRF = 315MHz, 345MHz, or

433.92MHz, TA = -40°C to +125°C, unless otherwise noted. Typical values are at AVDD = DVDD = HVIN = PAVDD = +2.7V, TA = +25°C,

unless otherwise noted.) (Note 1)
