MAX3744 - Maxim Integrated Products

MAX3744 (MAX3744 / MAX3745) SFP Transimpedance Amplifiers

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.

Features

allow easy assembly into a low-cost TO-46 or TO-56 header with a photodiode. The MAX3744 and MAX3748A receiver chip set provides an RSSI output using a Maxim-proprietary
* interface technique. The MAX3744 preamplifier, MAX3748A postamplifier, and DS1858/DS1859 SFP controller meet all the SFF-8472 digital diagnostic requirements. o Up to 2.7Gbps (NRZ) Data Rates o RSSI Implementation in 4-Pin TO46 Header (MAX3744) o 10psP-P Deterministic Jitter for <100µAP-P Input Current o 330nARMS Input-Referred Noise at 2.1GHz Bandwidth o 28mA Supply Current at +3.3V o 2GHz Small-Signal Bandwidth o 2.0mAP-P A.
