Part Details:

19-2927; Rev 2; 11/05 2.7Gbps SFP Transimpedance Amplifiers with RSSI MAX3744/MAX3745 General Description Features The MAX3744/MAX3745 transimpedance amplifiers pro- Up to 2.7Gbps (NRZ) Data Rates vide a compact, low-power solution for communicationup to 2.7Gbps. They feature 330nA input-referred noise RSSI Implementation in 4-Pin TO46 Header at 2.1GHz bandwidth (BW) with 0.85pF input capaci- (MAX3744) tance. The parts also have >2mAP-P AC input overload. 10psP-P Deterministic Jitter for <100µAP-P Input Both parts operate from a single +3.3V supply and con- Current sume 93mW. The MAX3744/MAX3745 are in a compact 330nA 30-mil x 50-mil die and require no external compensa- RMS Input-Referred Noise at 2.1GHz tion capacitor. A space-saving filter connection is pro- Bandwidth vided for positive bias to the photodiode through an 28mA Supply Current at +3.3V on-chip 580 resistor to VCC. These features alloweasy assembly into a low-cost TO-46 or TO-56 header 2GHz Small-Signal Bandwidth with a photodiode. 2.0mAP-P AC Overload The MAX3744 and MAX3748A receiver chip set pro- Die Size: 30 mils x 50 mils vides an RSSI output using a Maxim-proprietary* inter-face technique. The MAX3744 preamplifier, MAX3748Apostamplifier, and DS1858/DS1859 SFP controller meetall the SFF-8472 digital diagnostic requirements.
