Overview

45nA_RMS Noise, -33dBm Sensitivity
18.3kΩ Transimpedance Gain
580MHz Bandwidth
2mA_P-P Input Overload, 1dBm Overload
66mW Power Dissipation
3.3V Operation
Average Photocurrent Monitor

The MAX3658 is a transimpedance preamplifier for receivers operating up to 622Mbps. Low noise, high gain, and low power dissipation make it ideal for fiber access and small form-factor transceivers.

The MAX3658 features 45nA input-referred noise, 18kΩ transimpedance gain, 580MHz bandwidth, and 2mA_P-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.

Applications

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