iT3018E

iT3018E 12.5-Gb/s High-Gain RX Limiter Amplifier Description The iT3018E is a RoHS-6-compliant limiting amplifier for use as a post amplifier in OC192 and STM-64 optical receivers. Differential signals as small as +/-6 mVpp can be amplified to 2.2 Vpp differential. The device includes offset correction and output voltage control. Both AC and DC coupling are allowed at both input and output. The high sensitivity of the iT3018E allows the device to be used at the output of a transimpedance amplifier. ¾ 3 dB bandwidth: 10 GHz ¾ Differential gain: 50 dB ¾ Saturated output: 1.1 Vpp, each output into 50 ohms ¾ Input sensitivity 3.0 mVpp at BER<1E-12 ¾ Single bias supply: -5.2 V ¾ Power consumption: 624 mW ¾ Bias current: 120 mA ¾ DC offset correction ¾ Amplitude voltage control ¾ Low RMS jitter ¾ RoHS-6-compliant 4x4 mm QFN (MO-220) package Features www.DataSheet4U.com Absolute Maximum Ratings S ymbol Vee1,2 Vd Vm Tch Tstg Parameters/conditions Pow er supply voltage Applied voltage at data input (differential) Applied voltage at data input (single ended) Maximum channel temperature Storage temperature Min. -8 Max. 0 3 1.5 5 150 Units V V V mA o Ioffset(+),(-) Offset control current -65 C 150 °C Recommended Operating Conditions Sym bol Tc Vee1 Vee2 Iee1+Iee2 Voffset (+) Voffset (-) Vctrl Vd Vm Vindc R Param eters/conditions Operating temperature range (Tcase) Pow er supply voltage Pow er supply voltage Total bias supply current Offset control voltage Offset control vol...
