ISDB-T Single-Segment Low-IF Tuners
DC ELECTRICAL CHARACTERISTICS (continued)
(MAX2160 EV kit, VCC = +2.7V to +3.3V, VGC1 = VGC2 = 0.3V (maximum gain), no RF input signals at RFIN, baseband I/Os are open
circuited and VCO is active with fLO = 767.714MHz, registers set according to the recommended default register conditions of
Tables 2–11, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VCC = +2.85V, TA = +25°C, unless otherwise
noted.) (Note 1)
