iT3010E

iT3010E 10 GHz Medium-Gain Differential Amplifier Description The iT3010E is a RoHS-6-compliant packaged differential amplifier designed for use in 10.7 Gb/s and 12.5 Gb/s (OC-192) optical transmitters and receivers as a gain stage with limiting functionality. It allows single-ended input signals from 350 mVpp up to 900 mVpp, or differential signals from 250 mVpp to 1800 mVpp to be limited at a constant differential output voltage of 3.8 Vpp. The iT3010E can be used as predriver for OC-192 optical modulator driver amplifiers. Output voltage control and external offset correction are provided. The amplifier also provides excellent linear performance when operating at lower output voltage. Both AC and DC input coupling are allowed. DC-coupled SCFL differential input (input HIGH voltage = 0 V, and input LOW voltage = -900 mV) are allowed. ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ Limiting function with 3.8 Vpp differential output 3 dB Bandwidth: 10 GHz Differential gain: 23.5 dB Standard bias supply: -5 V or -5.2V, +5 V Power consumption: 855 mW <1% total harmonic distortion at Pout = 0 dBm Low group delay Low jitter Output voltage control AC and DC input coupling (SCFL compatible) AC and DC output coupling RoHS-6-compliant 4x4 mm QFN (MO-220) package Sym bol Vee Vcc Vd Vm IDCin (+),(-) Tch Tstg Param eters/conditions Pow er supply voltage Pow er supply voltage Applied voltage at data input (differential) Applied voltage at data input (single ended) Offset control current Maximum channel temperat...
