The MAX3910 is a 10.7Gbps transimpedance amplifier designed for SONET OC-192/SDH STM-64, DWDM, and 10Gbps systems employing optical amplifiers. Operating from a single +5V or -5.2V supply, it converts a photodiode current into a measurable differential voltage. This product has a linear gain for an input current up to 950AP-P and a soft-limiting feature that provides an increasing output swing for an input current up to the 3.5mAP-P overload. An offset adjust circuit and output- level monitors allow system threshold adjustments. Additional features include back-terminated 50 outputs and an integrated 200 filter resistor to bias the photodiode.
The MAX3910 has a small-signal bandwidth of 9.1GHz and a small-signal transimpedance of 1.65k. The part achieves an input sensitivity of 15.5AP-P for a BER of 10-12, translating to an optical sensitivity of -19.3dBm for a PIN (r = 0.9, re = 6.6) photo detector and -28.8dBm for an APD (M = 8, = 0.9, re = 10) photo detector.
The MAX3910 is fabricated in Maxim's in-house SiGe process and is available in die form.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
