ABSOLUTE MAXIMUM RATINGS

DC ELECTRICAL CHARACTERISTICS

(VCC = LO_VCC = 2.7V to 3.3V, TA = -20°C to +85°C, unless otherwise noted.)

AC ELECTRICAL CHARACTERISTICS

(VCC = LO_VCC = 3.0V, fOSC = 140MHz, ENABLE = 2.6V, fII = fQQ = 600kHz, TA = -20°C to +85°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.

Note 1: Guaranteed by design, not tested.

Note 2: The frequency range can be extended in either direction, but has not been characterized. At higher frequencies, the IF

output level may decrease and distortions may increase.
