AC ELECTRICAL CHARACTERISTICS (continued)
MAX2117 Evaluation Kit: VCC = +3.13V to +3.47V, VGC1 = +0.5V (max gain), TA = 0°C to +70°C. Default register settings except
BBG[3:0] = 1011. Typical values measured at VCC = +3.3V, TA = +25°C, unless otherwise noted.) (Note 1)

Note 1: Min/max values are production tested at TA = +70°C. Min/max limits at TA = 0°C and TA = +25°C are guaranteed by design
and characterization.
Note 2: Gain-control 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
1000MHz to 5MHz baseband (fLO = 995MHz). Baseband gain is set to its default value (BBG[3:0] = 1011). Two tones at
-26dBm each are applied at 999MHz and 1000MHz. 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
1000MHz to 5MHz baseband (fLO = 995MHz). Baseband gain is set to its default value (BBG[3:0] = 1011). Two tones at
-20dBm each are applied at 895MHz and 800MHz. 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 1000MHz
to 5MHz baseband (fLO = 995MHz). Baseband gain is set to its default value (BBG[3:0] = 1011). Two tones at -20dBm each
are applied at 470MHz and 795MHz. 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 1000MHz
27.5Mbaud signal at -55dBm. GC2 set for mid-scale. The test signal will be set for PR = 7/8 and SNR of -8.5dB. An adjacent
channel at ±40MHz is added at -25dBm. DVB-S BER performance of 2E-4 will be maintained for the desired signal. GC2
may be adjusted for best performance.
Note 7: Guaranteed by design and characterization at TA = +25°C.
Note 8: See Table 14 for crystal ESR requirements.
