Analog Devices- New Transimpedance Amplifier Optimized For Cost-Effective 10-Gbps Optical Networks

Facilitates design and assembly of TO-can-based ROSAs while providing best-in-class performance

Sept 18, 2003 - Analog Devices - The ADN2821 3.3 V transimpedance amplifier (TIA) is designed for use in small form-factor receiver packages in 10-Gbps optical networks. In the past, optical receivers operating at high data rates required expensive, large footprint, ceramic-based packages. With the continuing cost pressures in optical networking, a key trend has been the demand for smaller, more cost-effective packaging. The ADN2821 successfully addresses the size, cost, and performance requirements of today's 10-Gbps receive optical subassemblies (ROSAs).
Featuring unrivaled sensitivity, high transimpedance and low power consumption on a 3.3 V power supply, the ADN2821 provides exceptional performance up to 11.1 Gbps. The layout and design of the ADN2821 are optimized to specifically address the space and performance concerns of TO-can-based ROSAs. The on-chip photodiode filter network and average power monitor allow many discrete components to be eliminated. By easing design and minimizing cost, the ADN2821 provides an ideal solution for 10-Gbps ROSA equipment manufacturers.

Applications
The ADN2821 is designed for 10.7-Gbps optical receiver modules using small form-factor packages.

Pricing and Availability
The ADN2821 is now available and priced at $34.50 per unit in 1,000-piece quantities.
