2 / 20 page 300MHz to 450MHz Frequency-Programmable ASK/FSK Transmitter 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS DC ELECTRICAL CHARACTERISTICS ( Typical Application Circuit, 50 Ω system impedance, tuned for 315MHz to 433.92MHz operation, VAVDD = VDVDD = VPAVDD = +2.1V to +3.6V, fRF = 300MHz to 450MHz, fCRYSTAL = 16MHz, TA = -40°C to +125°C, unless otherwise noted. Typical values are at VAVDD = VDVDD = VPAVDD = +2.7V, TA = +25°C, unless otherwise noted. All min and max values are 100% tested at TA = +125°C, and guaranteed by design and characterization over temperature, unless otherwise noted.) Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
