Keep unused units in conductive foam or shunt the terminals together. Discharge the conductivefoam to the destination socket before insertion.Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functionaloperation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure toabsolute maximum rating conditions for extended periods may affect device reliability.ELECTRICAL CHARACTERISTICS(V = 4.75V to 5.25V, T = +25°C, unless otherwise noted.)CC APARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITSDC SPECIFICATIONS (V = System Ground, V = V = 5.0V ±5%)GND CCA CCDDigital Supply Current I V , V , V , V 102 mACCD CCA CCO CCD CCCADC Supply Current I V 80 mACCAD CCADRF Blocks Supply Current I V , V , V , V 170 mACCRF CCIF CC2 CC1 CCQIF Port DC Dynamic Range V 0.5 100 mVIFIF Port Input Resistance R 40 75 ΩIFV V = 100mV 1.0 1.5AGMIN IFAGC Input Voltage VV V = 0.5mV 2.3 2.9AGMAX IFAGC Input Resistance R 50 100 kΩAGCAGC Input Capacitance C (Note 2) 2 pFAGCAGC Range AGCR 40 dBAGC Control Slope Variation SV Variation dB/V 4:1AGCAGC Control Input Bias Current I Voltage range = 1V to 4V ±20 µAAGCLowpass Filter Tune Input Resistance R 10 kΩILPFLowpass Filter Tune Input Capacitance C (Note 2) 2 pFILPFTNKA, TNKB Resonant Port Bias VoltageV 4.1V on complementary input 13 VLOLO Resonant Port Input Resistance R (Note 2) 10 kΩILOLO Resonant Port Input Capacitance C (Note 2) 2 pFILOLO Prescaler Output High (Note 3) V R = 1MΩ, C = 15pF 2.4 VOH L LLO Prescaler Output Low V R = 1MΩ, C = 15pF 0.5 VOL L LLO Prescaler Output Source Current I R = 1MΩ, C = 15pF, V = 2.4V 400 µAOH L L OLO Prescaler Output Sink Current I R = 1MΩ, C = 15pF, V = 0.5V 50 µAOL L L OBaseband Amplifier DC Gain A 27 29 31 dBVBBBaseband Input—Input Capacitance C (Note 2) 2 pFIBBBaseband Amplifier I/Q Offset MatchLSB = 24mV, ENOPB = 0V, V 1.0 LSBOFFBB(Note 4) V = V to VFTUNE FTMIN FTMAXBaseband Amplifier Offset AdjustR Voltage Range = 1V to 4V 10 kΩOFFBBInput Resistance2 _______MAX2101MAX21016-Bit Quadrature DigitizerFeaturesThe MAX2101 6-bit quadrature digitizer combines quad- ' ADCs Provide Greater than 5.5 Effective Bits at rature demodulation with analog-to-digital conversion on f = 60Msps, f = 15MHzS INTMa single bipolar silicon die.
