11-Gbps and 6-Gbps integrated optical receivers from ADI

Analog Devices Inc. (ADI) has introduced 11-Gbps and 6-Gbps integrated optical receivers. ADI says these are first such devices in the market.

ADN3000-06 and ADN3000-11 integrated optical receivers are made using ADI's XFCB high-speed complementary bipolar process on bonded SOI for the advantage of lesser external components and low power consumption.

ADI says the monolithic approach eliminates photodiode to TIA wire bonds allowing for a fully characterized solution that reduces design complexity and improves design reliability in fiber optic networks. The new optical receivers are fully compatible with normal incidence, standard telecom and datacom ROSAs (receive optical subassemblies) used today. The technology is extensible to multi-channel devices and will allow high-performance optical communications links to migrate to higher-volume applications, such as active optical cable and high-performance computing.

The ADN3000-06 and ADN3000-11 optical receivers consume 65 mW while running on a single 3.3-V power supply offering typical sensitivity of -19 dBm OMA (optical modulation amplitude) at 6 Gbps and -17dBm OMA at 11 Gbps.
