GENERAL DESCRIPTION

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.

FUNCTIONAL BLOCK DIAGRAM

Figure 1.

The ADN3000-06 also features an optical average power moni­toring 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.
