iT3012E

iT3012E 8 GHz Differential-to-Single-Ended Amplifier Description The iT3012E is a RoHS-6-compliant packaged differential-to-single-ended amplifier designed for use as an optical modulator predriver with limiting functionality in 10.7 Gb/s and 12.5 Gb/s (OC-192) optical transmitters and receivers. It allows single-ended input signals of 350 mVpp to 900 mVpp or differential signals of 250 mVpp to 1800 mVpp to be limited at a constant singleended output voltage of 1.9 Vpp. It provides output voltage control and allows external offset correction. iT3012E also provides excellent linear performance when operating at lower output voltages. Both AC and DC input coupling are allowed. DC-coupled SCFL differential input (input “high” voltage = 0 V, input “low” voltage = -900 mV) is allowed. ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ Limiting function with 1.9 Vpp single-ended output 3 dB bandwidth: 8 GHz Single-ended Gain: 17.5 dB Standard bias supply levels: -5 V or -5.2 V, +5 V Power consumption: 665 mW Low group delay and jitter Output voltage control AC and DC input coupling (SCFL compatible) AC and DC output coupling Features www.DataSheet4U.com RoHS-6-compliant 4x4 mm QFN (MO-220) package Absolute Maximum Ratings 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 temperature Storage temperature Min. -8 0 Max. ...
