MAX3658AETA+T

The MAX3658 transimpedance amplifier is designed for 622Mbps fiber optic applications. The MAX3658 is comprised of a transimpedance amplifier, a voltage amplifier, an output buffer, a DC cancellation circuit, and a photocurrent monitor.

Applications

• Optical Receivers (Up to 622Mbps Operation)
• Passive Optical Networks
• SFF/SFP Transceivers
• FTTx Transceivers

Key features

• The MAX3658 features 45nA input-referred noise, 18KΩ transimpedance gain, 580MHz bandwidth, and 2mAP-P input overload.
• Operating from a +3.3V supply, the MAX3658 consumes only 66mW.
• An integrated filter resistor provides positive bias for the photodiode.
• These features, combined with a small die size, allow easy assembly into a TO-46 header with a photodiode.
• The MAX3658 also includes an average photocurrent monitor.
• The MAX3658 has typical optical sensitivity of -33dBm (0.9A/W), which exceeds the class-B APON requirements.
• Typical optical overload is 1dBm.
• The MAX3658 is available in die form with both output polarities (MAX3658A and MAX3658B).
• The MAX3658A is also available in a 3mm x 3mm 8-pin TDFN package.
• 45nARMS Noise, -33dBm Sensitivity
• 18.3kΩ Transimpedance Gain
• 580MHz Bandwidth
• 2mAP-P Input Overload, 1dBm Overload
• 66mW Power Dissipation
• 3.3V Operation
• Average Photocurrent Monitor
