MAX3724, MAX3725
3.2Gbps SFP Transimpedance Amplifiers with RSSI
|
Status
All versions are No Longer Available.
Description
The MAX3724/MAX3725 transimpedance amplifiers provide a compact, low-power solution for communication up to 3.2Gbps. They feature 325nA input-referred noise at 2.1GHz bandwidth (BW) with 0.6pF input capacitance. The parts also have > 2mAP-P AC input overload.
Both parts operate from a single +3.3V supply and consume 93mW. The MAX3724/MAX3725 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 580Ω resistor to VCC. These features allow easy assembly into a low-cost TO-46 or TO-56 header with a photodiode.
The MAX3724 and MAX3748A receiver chip set provides an RSSI output using a Maxim interface technique. The MAX3724 preamplifier, MAX3748A postamplifier, and the DS1858/DS1859 SFP controller meet all the SFF-8472 digital diagnostic requirements.
