Transceiver Solutions Alaska® X Dual 10 Gigabit XAUI to XGMII Transceiver Octal 3.1875 Gbps SERDES 88X2080 PRODUCT OVERVIEW The Marvell¨ Alaska¨ X device (88X2080) is a CMOS Dual 10 Gigabit Ethernet XAUI and Octal 3.125/3.1875 Gbps SERDES device. The 88X2080 transceiver performs all of the necessary XAUI to XGMII functions for 10 Gigabit Ethernet (GbE) and 10 Gigabit Fiber Channel applications, while achieving very low power dissipation. The parallel and serial interfaces on the device are IEEE 802.3ae 10 Gigabit Media Independent Interface (XGMII) and 10 Gigabit Attachment Unit Interface (XAUI), respectively. The Alaska X device incorporates eight lanes operating up to 3.125/3.1875 Gbps, each with a selectable 8B/10B encoder/decoder. The eight lanes can operate independently from 1.0 to 3.1875 Gbps to support a variety of backplane applications or can be conÞgured as two 10 Gigabit XAUI channels. The device allows the use of either 62.5, 125 or 156.25/159.375 MHz reference inputs to provide ßexible clocking. In addition, the device can be conÞgured as a single XGMII to Dual XAUI device for redundancy applications. The device also supports XAUI repeater applications.

The device connects to optical modules such as XENPAK/XPAK MSA modules using the XAUI interfaces and to the switch devices using the XGMII interfaces. The Alaska X device features powerful amplitude and pre-emphasis controls, which allow the device to be used as a highly robust backplane SERDES. The device can operate over 60 inches of generic backplane PCB traces with multiple connectors making it ideal for chassis-based switching systems. The 88X2080 product is also well-suited for 10 Gigabit copper connections such as interconnect links between stackable switching systems, uplink connections and chassis-to-chassis connections. The Alaska X transceiver allows 10 Gigabit operation over standard copper cables such as 15 meters of standard InÞniBandª 8-pair cable. The 88X2080 device is ideally suited for the following applications: 1. Dual 10 GbE/10 Gigabit Fiber Channel links: Dual XGMII to Dual XAUI mode 2. Redundant 10 GbE/10 Gigabit Fiber Channel links: Single XGMII to Dual XAUI mode 3. XAUI retimer/repeater: XAUI to XAUI repeater mode 4. Backplanes: Octal SERDES modes The 88X2080 device seamlessly interfaces with the following: 1. XENPAK/XPAK/X2 optical modules 2. Copper cable 3. PCB traces 4.
