| 12.5 Gb/s High-Sensitivity Limiter Amplifier Description The IT3011E is a RoHS-6-compliant limiting amplifier for use as a post amplifier in OC-192 and STM-64 optical receivers. Signals as small as +/-7 mVpp differential can be amplified to 1.28 Vpp differential. Offset correction and output voltage control are provided. Both AC and DC coupling are allowed at the input and output. The high sensitivity allows the device to be used at the output of a transimpedance amplifier. 3-dB bandwidth: 10 GHz Differential gain: 42 dB Saturated output: 640 mVpp on each output into 50 ohms Input sensitivity 2.5 mVpp at BER<1E-12 Single bias supply: -5.2 V Power consumption: Less than 572 mW Bias current: 95 mA DC offset correction Amplitude voltage control Low RMS jitter degradation IT3011E Features www..com RoHS-6-compliant 4x4 mm QFN (MO-220) package Absolute Maximum Ratings Symbol Vee1, 2 Parameters/conditions Power supply voltage Applied voltage at data input Vd (differential) Applied voltage at data input (single Vm ended) Ioffset(+),(-) Offset control current Tch Tstg Maximum channel temperature Storage temperature Min. -8 Max. 0 3 1.5 5 Units V V V mA C C o -65 150 150 Recommended Operating Conditions Symbol Tc Vee1 Vee2 Iee1+Iee2 Voffset (+) Voffset (-) Vctrl Vd Vm Vindc Parameters/conditions Operating temperature range (Tcase) Power supply voltage Power supply voltage Total bias supply current Offset control voltage Offset control voltage Amplitude voltage control Applied peak to peak voltage at data input (differential) Applied peak to peak voltage at data input (single ended) Input/output interface DC input voltage (with DC-coupled input) Min. 0 -5.45 -5.45 80 -5 -5 -5.2 7 14 Typ. -5.2 -5.2 95 Max. 85 -4.95 -4.95 110 5 5 0 1000 1000 Units o C V V mA V V V mV mV V AC and DC coupled -0.5 0.5 For pricing, delivery, and ordering information, please contact GigOptix at (650) 424-1937, e-mail: sales@gigoptix.com, or visit our site at www.GigOptix.com. 1 12.5 Gb/s High-Sensitivity Limiter Amplifier Electrical Characteristics At ambient Temperature Vee1,2 = -5.2 V S ymbol P G B3dB RLin RLout Vin Vout Vout Parameters/conditions Power consumption Differential small signal gain 3 dB bandwidth Input return loss (up to 10 GHz) Output return loss (up to 10 GHz) Input sensitivity differential input (BER <1E-12, 223-1PRBS, 12.5 Gb/s) Output peak to peak voltage (either Q or /Q) (Vctrl = 0 V for max. output voltage) Vout sensitivity vs. bias (Vee = -5.2 V +/-5%) p g( p load) Rise time (20% - 80%) Fall time (20% - 80%) Jitter RMS Degradation Jrms*=(Jmeas^2-Jthru^2)^.5 Min. 416 41 9 12 10 +/-2.5 550 640 +/-11 -450 -350 21 17 1 -250 27 23 1.5 Typ. 494 42 10 20 15 Max. 572 Units mW dB GHz dB dB mVpp mVpp % mV ps ps ps IT3011E www..com Voutdc Trse Tfse Jrms* S-Parameter Data (Measured on connectorized evaluation board) Vee1 = Vee2 = -5.2 V Iee1+Iee2 = 95 mA iT3011 Single Ended Gain 48 44 40 36 32 28 24 20 16 12 8 4 0 0 2 4 6 8 10 12 14 16 18 0 -5 -10 -15 iT3011 Input Return Loss S21 (dB) S11 (dB) -20 -25 -30 -35 -40 -45 -50 0 2 4 6 8 10 12 14 16 18 Freq.
