ABSOLUTE MAXIMUM RATINGS

DC ELECTRICAL CHARACTERISTICS

(VCC1, VCC2 = +2.7V to +5.25V, FDBK = open, TANK = open, OUT and OUT connected to VCC through 50Ω, SHDN = 2V,

TA = -40°C to +85°C, unless otherwise noted. Typical values measured at VCC1 = VCC2 = 3.0V, TA = +25°C.) (Note 1)

AC ELECTRICAL CHARACTERISTICS

(Per Test Circuit of Figure 1, VCC = +3.0V, SHDN = VCC, ZLOAD = ZSOURCE = 50Ω, PIN = -20dBm (50Ω), fTEST = 900MHz,

TA = +25°C, 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.

Output Isolation

Note 2: Guaranteed by design and characterization at 10MHz, 650MHz, 900MHz, and 1050MHz. Over this frequency range, the

magnitude of the negative real impedance measured at TANK is greater than one-tenth the magnitude of the reactive

impedances at TANK. This implies proper oscillator start-up when using an external resonator tank circuit with Q > 10. C3

and C4 must be tuned for operation at the desired frequency.

Note 1: Specifications are production tested and guaranteed at TA = +25°C and TA = +85°C. Specifications are guaranteed by

design and characterization at TA = -40°C.
