APPLICATIONS
The Marvell Alaska single-port 88E1111 transceiver is the Trst in the industry to enable a copper 1000BASE-T Gigabit Small Form
Factor Pluggable (SFP) module, which is a hot-swappable, plug-and-play device used in Gigabit applications. The device features
physical dimensions of only 9 mm x 9 mm (96-pin BCC option), making it the only device small enough to physically Tt into
the SFP module. In addition, the 88E1111 device is the only transceiver to meet the stringent power requirements of the SFP
Multi-Source Agreement (MSA). Using the Alaska single-port 88E1111 product, systems manufacturers can now offer copper
versions, enabling systems to support both copper and Tber media interchangeably.
The Alaska single-port 88E1111 transceiver offers the most advanced feature set including VCT technology used to diagnose
the attached cable plant and isolate and report cable faults with one-meter accuracy. Additionally, the devices feature ò2-pair
downshiftó capability for plug-and-play operation in 2-pair cable environments, as well the Media Detect feature which supports
both copper and Tber media simultaneously. The 88E1111 product supports the GMII, RGMII, SGMII, TBI, and RTBI PHY/MAC
interface options.
THE MARVELL ADVANTAGE:
