The Marvell Alaska Ultra 88E1111-B2-CAA1C000 is a high-performance Gigabit Ethernet Transceiver designed for 1000BASE-T, 100BASE-TX, and 10BASE-T Ethernet applications. Manufactured using a standard digital CMOS process, this device integrates all necessary active circuitry for physical layer functions, enabling data transmission and reception over standard CAT 5 unshielded twisted pair cables.
Key features include support for multiple MAC interfaces such as GMII, TBI, RGMII, RTBI, and SGMII, as well as an integrated 1.25 GHz SERDES for 1000BASE-X fiber applications. The transceiver incorporates advanced digital adaptive equalizers, echo cancellers, and crosstalk cancellers for robust signal integrity. It also offers low power modes like Energy Detect and Energy Detect+, and diagnostic capabilities through three loopback modes.
Designed for flexibility, the 88E1111-B2-CAA1C000 operates with dual supplies of 2.5V and 1.0V, with I/Os tolerant to 3.3V. It is available in multiple package options, including 117-Pin TFBGA, 96-Pin BCC, and 128 PQFP, with TFBGA and BCC packages offered in Commercial or Industrial grades. The device is RoHS 6/6 compliant.
This component is suitable for various networking applications requiring reliable and efficient Ethernet connectivity. Its integrated features simplify board design and reduce component count, making it a valuable solution for network infrastructure, communication equipment, and embedded systems.
