MAX3658

19-3015; Rev 1; 5/04 622Mbps, Low-Noise, High-Gain Transimpedance Preamplifier General Description 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 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 Features MAX3658 Ordering Information PART MAX3658AETA MAX3658AE/D TEMP RANGE -40°C to +85°C — — PINPACKAGE 8 TDFN (3mm x 3mm) Dice* Dice* PKG CODE T833-1 — — Applications Optical Receivers (Up to 622Mbps Operation) Passive Optical Networks SFF/SFP Transceivers FTTx Transceivers ...
