CDMA IF VGAs and I/Q Demodulators
with VCO and Synthesizer
AC ELECTRICAL CHARACTERISTICS (continued)
(MAX2310/MAX2314 or MAX2312/MAX2316 EV kit, VCC = +2.75V, registers set to default power-up states, fIN = 210.88MHz for
CDMA, fIN = 85.88MHz for FM, fREF = 19.68MHz, synthesizer locked with passive 2nd-order lead-lag loop filter, SHDN = high, VGC
set for +35dB voltage gain, differential output load = 10kΩ, all power levels referred to 50Ω, TA = +25°C, unless otherwise noted.)

FM_IQ and FM_I modes are not available on MAX2312 and MAX2316.
Recommended operating frequency range.
f1 = 210.88MHz, f2 = 210.89MHz, Pf1 = Pf2 = -15dBm.
f1 = 210.88MHz, f2 = 210.89MHz, Pf1 = Pf2 = -50dBm.
Small-signal gain at 200kHz below the LO frequency will be reduced by less than 0.25dB when an interfering signal at
1.25MHz below the LO frequency is applied at the specified level.
Guaranteed by design and characterization.
f1 = 85.88MHz, f2 = 85.98MHz, Pf1 = Pf2 = -15dBm.
f1 = 85.88MHz, f2 = 85.98MHz, Pf1 = Pf2 = -50dBm.
Measured at LOOUT with BD = 0 (÷2 selected).
