iT3012

iT3012 8 GHz, Differential-to-Single-Ended Amplifier Description The iT3012 is a 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 single-ended output voltage of 1.9 Vpp. It provides output voltage control and allows external offset correction. iT3012 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. www.DataSheet4U.com Features ™ 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 Low-cost JEDEC QFP-N (MO-220) package Absolute Maximum Ratings Sym bol Vee Vcc Vd Vm IDC IN Param eters/conditions Pow er supply voltage Pow er supply voltage Applied voltage at data input (differential) Applied voltage at data input (single ended) Min. -8 0 Max. 0 8 3 1.5 5 150 Units V V V V mA °C °C (+),(-) Offset control current Maximum channel temperature Storage temp...
