2 / 18 page Complete Direct-Conversion L-Band Tuner 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS DC ELECTRICAL CHARACTERISTICS (MAX2121 Evaluation Kit: VCC_ = +3.13V to +3.47V, fXTAL = 27MHz, TA = -40°C to +85°C, VGC1 = +0.5V (max gain), default register settings except BBG[3:0] = 1011. No input signals at RF, baseband I/Os are open circuited. Typical values measured at VCC = +3.3V, TA = +25°C, unless otherwise noted.) (Note 1) 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.
