MAX3277：Low-Noise, Fibre Channel Transimpedance Amplifiers

The MAX3275/MAX3277 transimpedance amplifiers provide a compact low-power solution for communication up to 2.125Gbps. They feature 300nA input-referred noise at 2.1GHz bandwidth (BW) with 0.85pF input capacitance. The parts also have 2mAP-P AC input overload. The MAX3277 is identical to the MAX3275, but with the output polarities inverted for optimum packaging flexibility. Both parts operate from a single 3.3V supply and consume only 83mW. The MAX3275/MAX3277 are compact 24mil x 47mil die and require no external compensation capacitor. A space-saving filter connection is provided for positive bias to the photodiode through an on-chip 600Ω resistor to VCC. These features allow easy assembly into a TO-46 or TO-56 header with a photodiode. The MAX3275/MAX3277 and MAX3274 limiting amplifiers provide a two-chip solution for dual-rate, fibre channel receiver applications.
