PRODUCT OVERVIEW
The Marvell¨Alaska¨X devices (88X2010 and 88X2011) are CMOS 10 Gigabit Ethernet (GbE) serial interface
transceivers. The 88X2010 transceiver provides dedicated 10 GbE and 10 Gigabit Fibre Channel (GFC) LAN PHY
serial operation. The 88X2011 device incorporates WAN Interface Sublayer (WIS) functionality and can be used
for LAN and WAN PHY applications. WIS functionality enables the transmission of Ethernet data over SONET
networks. These transceivers perform all of the necessary serial 10 Gbps to XAUI conversion functions, while
achieving a very low power dissipation of 2.0 Watts. The parallel and serial interfaces on the device are IEEE
802.3ae 10 Gigabit Attachment Unit Interface (XAUI) and PMA serial interface (XFI compliant), respectively.
The Alaska X devices incorporate serial 10 Gbps and XAUI Serializer/Deserializer (SERDES) with on-chip clock
generation and recovery. In addition, the devices feature IEEE 802.3ae compliant PCS, PMA, WIS, and XGXS
functionality. Both the 88X2010 and 88X2011 devices support industry standard management interface through
their MDIO ports. The devicesÕ small form factor and low power consumption make them ideal for XENPAK, XPAK
and X2 fiber optic modules. The 88X2010 and 88X2011 devices are also suitable for XFP module-based applications.

APPLICATIONS
The Marvell Alaska X transceiver operates as the serial to XAUI converter between opto-electronic components and the XAUI
PCB interface in 10 GbE and 10 GFC in XENPAK, XPAK and X2 optical modules. The device also connects to serial interface
optical modules using a XFI interface and to the switch devices using a XAUI to XGMII interface components such as the
88X2040 device. The 88X2010 and 88X2011 devices also include a Link Alarm Status Interrupt (LASI) to simplify diagnostics
for multi-source agreement (MSA) requirements in 10 GbE optical modules.
The 88X2011 transceiver WIS includes:
¥Payload mapping
¥Path, line and section overhead (A1, A2 Framing)
¥B1, B2 and B3 generation and checking
¥Scrambling and descrambling
The device is also well-suited for use with discrete optics and physical media semiconductor devices. Manufacturers can optimize
fiber optic connections to achieve lower cost or optimize the optics for the application.
The 88X2010/88X2011 devices are ideally suited for the following applications:
1. 10 GbE LAN PHY: XAUI to 10.3125 Gbps serial interface
2. 10 GbE WAN PHY: XAUI to 9.953 Gbps serial interface (88X2011 only)
3. 10 GFC: XAUI to 10.51875 Gbps serial interface
The 88X2010/88X2011 devices seamlessly interface with the following:
1. XFP optical modules
2. Laser diode drivers/electro-absorption modulator drivers
3. Transimpedance amplifiers
4. Transmitter and receiver optical sub-assemblies
