ISDB-T Single-Segment Low-IF Tuners
AC ELECTRICAL CHARACTERISTICS (continued)
(MAX2160 EV kit, VCC = +2.7V to +3.3V, fRF = 767.143MHz, fLO = 767.714MHz, fBB = 571kHz, fXTAL = 16MHz, VGC1 = VGC2 = 0.3V
(maximum gain), registers set according to the recommended default register conditions of Tables 2–11, RF input signals as speci-
fied, baseband output load as specified, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VCC = +2.85V,
TA = +25°C, unless otherwise noted.) (Note 1)
