6.144 Gbps Transimpedance Amplifier with Integrated Photodiode

The ADN3000-06 is a complete high speed optical receiver featuring a proprietary large-area germanium PIN photodiode integrated with a transimpedance amplifier (TIA). The integration of the photodiode eliminates bond wires between the diode and TIA that provides guaranteed performance and improved manufacturing reliability. The ADN3000-06 supports data rates of up to 6.5 Gbps for telecommunication and point-to-point LAN applications, and a wide range of operating wavelengths from 830 nm to 1560 nm.

The ADN3000-06 also features an optical average power moni-toring circuit that generates a voltage output proportional to the average photodiode current.

Typical power consumption of ADN3000-06 is 65 mW from a single 3.3 V supply. In saturated output, the signal has a typical differential amplitude of 240 mV p-p.

The ADN3000-06 is available in die form, and it is operational over the extended industrial temperature range of −40°C to +85°C.
