AC ELECTRICAL CHARACTERISTICS (continued)
(MAX2112 Evaluation Kit: V CC = +3.13V to +3.47V, T A = 0°C to +70°C (MAX2112CTI+), T A = -40°C to +85°C (MAX2112ETI+), default
register settings except BBG[3:0] = 1011. Typical values measured at V CC = +3.3V, T A = +25°C.) (Note 1)

Note 1: MAX2112CTI+: Min/max values are production tested at T A = +70°C. Min/max limits at T A = 0°C and T A = +25°C are
guaranteed by design and characterization.
MAX2112ETI+: Min/max values are production tested at T A = +85°C. Min/max limits at T A = -40°C and T A = +25°C are
guaranteed by design and characterization.
Note 2 : Input gain range specifications met over this band.
Note 3 : In-band IIP3 test conditions: GC1 set to provide the nominal baseband output drive when mixing down a -23dBm tone at
2175MHz to 5MHz baseband (f LO = 2170MHz). Baseband gain is set to its default value (BBG[3:0] = 1011). Two tones at
-26dBm each are applied at 2174MHz and 2175MHz. The IM3 tone at 3MHz is measured at baseband, but is referred to the
RF input.
Note 4 : Out-of-band IIP3 test conditions: GC1 set to provide nominal baseband output drive when mixing down a -23dBm tone at
2175MHz to 5MHz baseband (f LO = 2170MHz). Baseband gain is set to its default value (BBG[3:0] = 1011). Two tones at
-20dBm each are applied at 2070MHz and 1975MHz. The IM3 tone at 5MHz is measured at baseband, but is referred to the
RF input.
Note 5 : Input IP2 test conditions: GC1 set to provide nominal baseband output drive when mixing down a -23dBm tone at 2175MHz
to 5MHz baseband (f LO = 2170MHz). Baseband gain is set to its default value (BBG[3:0] = 1011). Two tones at -20dBm
each are applied at 925MHz and 1250MHz. The IM2 tone at 5MHz is measured at baseband, but is referred to the RF input.
Note 6 : Adjacent channel protection test conditions: GC1 is set to provide the nominal baseband output drive with a 2110MHz
27.5Mbaud signal at -55dBm. GC2 set for mid-scale. The test signal shall be set for PR = 7/8 and SNR of -8.5dB. An adja-
cent channel at ±40MHz is added at -25dBm. DVB-S BER performance of 2E-4 shall be maintained for the desired signal.
GC2 may be adjusted for best performance.
Note 7 : Guaranteed by design and characterization at T A = +25°C.
Note 8 : See Table 16 for crystal ESR requirements.
