The transmitter input and receiver output impedance is 100 Ohms differential.Data lines are internally AC coupled.The module provides differential termination and reduce differential to common mode conversion for quality signal termination and low EMI.Pin definition:The SFP+ modules are hot-pluggable. Hot pluggable refers to plugging in or unplugging amodule while the host board is powered. The SFP+ host connector is a0.8 mm pitch 20 position right angle improved connector specified by SFF-8083, or stacked connector with equivalent with equivalent electrical performance. Host PCB contact assignment is shown in Figure 2and contact definitions are given in Table 2. SFP+ module contacts mates with the host in the order of ground, power, followed by signal as illustrated by Figure 3and the contact sequence order listed in Table 2.Table 2: SFP+ Module PIN DefinitionAbsolute maximum ratingThese values represent the damage threshold of the module. Stress in excess of any of the individual Absolute Maximum Ratings can cause immediate catastrophic damage to the module even if all other parameters are within Recommended Operating Conditions.ParametersSymbolMin.Max.UnitPower Supply VoltageVCC0+3.6VStorage TemperatureTc-40+85°COperating Case TemperatureTc0+70°CRelative HumidityRH595%Table 3: Absolute Maximum RatingRecommended operating environmentRecommended Operating Environment specifies parameters for which the electrical and optical characteristics hold unless otherwise noted.ParameterSymbolMin.TypicalMaxUnitPower Supply VoltageVCC3.1353.3003.465VOperating Case TemperatureTC02570°CTable 4: Recommended Operating EnvironmentLOW Speed CharacteristicsParameterSymbolMin.TypicalMaxUnitPower Consumption1.21.2WTX_Fault,RX_LOSVOL00.4VVOHHost_Vcc-0.5Host_Vcc+0.3VTX_DISVIL-0.30.8VVIH2.0VCCT+0.3VRS0,RS1VIL-0.30.8VVIH2.0VCCT+0.3Electrical characteristicsTransmitter Input Characteristics ParameterConditionsSymbolMin.TypicalMaxUnitNominal Data RateVID2.1258.58.5GbdReference Differential Input ImpedanceZd100ΩInput AC Common Mode Input Voltage025mV(RMS)Differential Input Voltage SwingVID150900mVDifferential Input S-parameter0.01-3.9GHzSDD11-10dB3.9-8.5GHzNote1Note1Differential to Common Mode Conversion Note 20.01-8.5GHzSCD11-10dBData Dependant JitterDDJ0.1UI(p-p)Total JitterTJ0.28UI(P-P)Uncorrelated JitterUJ0.023RMS1) Differential Return Loss given by equation SDD11(dB) =-8+13.33 Log10(f/5.5), with fin GHz2) Common mode reference impedance is 25.
