AC ELECTRICAL CHARACTERISTICS (continued)
(MAX3580 EV kit, VCC = +3.1V to +3.5V, VGND = 0V. VRF_AGC = VBB_AGC = +2.85V, RF input terminated into a 75 load, BBI_ and
BBQ_ loaded by RL greater than 2k and CL less than 10pF, VCO active, registers are set according to the recommended default
register conditions, unless otherwise noted. Typical values are at VCC = +3.3V, TA = +25°C, unless otherwise noted.) (Note 1)
