Analog Devices Intros New AD8159 Switching Solution
Analog Devices Inc. (ADI, Wilmington, MA) introduced its new AD8159 switching solution, the newest member of ADI's X-stream™ family of switching solutions, which is designed to address 10 GB Ethernet Attachment Unit Interface port redundancy. A failsafe mechanism for maintaining high-system availability, redundancy is typically built into the ASIC switch fabric.
The AD8159 switch is configured as a quad multiplexer/demultiplexer that supports data rates of up to 3.2 Gbps, making it well-suited for the protocols of storage, enterprise, metro and core networking applications, including fibre channel, SATA, SONET and Ethernet.
The AD8159 consists of a two-port multiplexer and a two-port demultiplexer. Each port is a four-lane link, where each lane operates at up to 3.2 Gbps independent of the other lanes. The operation is optimized for non-return to zero data rates up to 3.2 Gbps per lane. The AD8159 has low power dissipation, typically 1 W at 3.3 V with output pre-emphasis and input equalization active on all lanes.
The AD8159 is sampling now and will be available in production quantities in August 2005. The AD8159 is packaged in a 100-lead TQFP package, and is priced at $11.95 per unit in 1000-piece quantities.
