2.7Gbps SFP Transimpedance Amplifiers with RSSI
General Description
The MAX3744/MAX3745 transimpedance amplifiers provide a compact, low-power solution for communication up to 2.7Gbps. They feature 330nA input-referred noise at 2.1GHz bandwidth (BW) with 0.85pF input capacitance. The parts also have >2mAP-P AC input overload. Both parts operate from a single +3.3V supply and consume 93mW. The MAX3744/MAX3745 are in a compact 30-mil x 50-mil die and require no external compensation capacitor. A space-saving filter connection is provided for positive bias to the photodiode through an on-chip 580 Ω resistor to V CC. These features allow easy assembly into a low-cost TO-46 or TO-56 header with a photodiode.
