iT3011

iT3011 12.5 Gb/s High-Sensitivity Limiter Amplifier Description The iT3011 is a 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: 494 mW ™ Bias current: 95 mA ™ DC offset correction ™ Amplitude Voltage Control ™ Low RMS jitter ™ Low-cost JEDEC QFP-N (MO-220) package Features www.DataSheet4U.com Absolute Maximum Ratings S ymbol Vee1,2 Vd Vm T ch T stg Parameters/conditions Power 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 Symbol Tc Vee1 Vee2 Iee1+Iee2 Voffset (+) Voffset (-) Vctrl Vd Vm Vindc Parameters/conditions Operating temperature range (T case) Power supply voltage Power supply voltage T otal bias supply current Offset control voltage Offset control voltage Amplitude voltage control Applied peak ...
