Transceiver Solutions Alaska® X 10 Gigabit Serial to XGMII Transceiver 88X2012 PRODUCT OVERVIEW TXD[31:0] TXC[3:0] TX_CLK RXD[31:0] RXC[3:0] RX_CLK FIFO 64B/66B Encoder Serializer FIFO 64B/66B Decoder Deserializer TBG/Clock Synthesizer MDC MDIO INTn Management Interface Registers S_OP S_ON XFP_CLKP XFP_CLKN S_IP S_IN XFI Interface XGMII Interface The Marvell¨ Alaska¨ X device (88X2012) is a CMOS 10 Gigabit serial interface transceiver. The 88X2012 transceiver provides dedicated 10 Gigabit Ethernet (GbE) and 10 Gigabit Fibre Channel (GFC) LAN PHY serial operation. This transceiver performs all of the necessary serial to XGMII functions, while achieving a very low power dissipation of 1.0 Watt. The parallel and serial interfaces on the device are IEEE 802.3ae 10 Gigabit Media Independent Interface (XGMII) and PMA serial interface (XFI compliant), respectively. The Alaska X device incorporates on-chip clock generation and recovery. The parallel interface is implemented with XGMII HSTL I/O. The 88X2012 device eliminates the XAUI interface thereby improving power consumption and data latency. The device supports industry standard management interface through its MDIO port. The highspeed serial interface allows direct interface with XFP MSA serial fiber optic modules, or can be directly interfaced with optical drivers and receivers.

The device connects to serial interface optical modules using the XFI interface and to the switch devices using the XGMII interface. The Alaska X supports a simplified architecture for 10 GbE and 10 GFC applications using an XFP MSA or similar serial optical module. Serial data is converted directly to XGMII format without using unnecessary interfaces and coding, such as XSBI and XAUI/XGXS. This results in a low power solution with minimal latency. 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 88X2012 device is ideally suited for the following applications: 1. 10 GbE links: XGMII to 10.3125 Gbps serial interface 2. 10 GFC: XGMII to 10.51875 Gbps serial interface 3. 10 Gigabit performance monitor: receive only The 88X2012 product seamlessly interfaces with the following: 1. XFP optical modules 2. Laser diode drivers/electro-absorption modulator drivers 3. Transimpedance amplifiers 4.
