2.5Gbps Transimpedance Amplifier

The MAX24011 is a low-power and high-sensitivity 2.5Gbps continuous mode transimpedance amplifier (TIA) optimized for GPON fiber optic applications.

The MAX24011 implements a complete analog front-end, converting the photo-detector current to a differential analog voltage signal.

The MAX24011 has a low-noise front-end, an AGC and typical differential transimpedance of 23kΩ. The MAX24011 also provides a filtered bias current to the photo detector cathode for internally biased PIN applications and a received signal strength indicator (RSSI) output. The RSSI is either derived from the current supplied by the PDC regulator, or represents the average current into the PDA pin for use with externally biased photodetectors, such as an APD.

The MAX24011 is available in die form for mounting on a header to create a ROSA when combined with suitable optics and photo-detector diode.
