Overview:

The 88E1111-B2-NDC2I000 is a high-performance Gigabit Ethernet transceiver from Marvell's Alaska Ultra family, designed for 10/100/1000BASE-T and 1000BASE-X applications. This physical layer (PHY) device integrates a single-chip transceiver with support for copper (1000BASE-T) and fiber (1000BASE-X) modes, making it highly versatile for a wide range of networking applications . The device is fabricated using advanced CMOS technology and is housed in a compact, green 9 mm × 9 mm, 96-pin QFN (Quad Flat No-Lead) package with an exposed pad for enhanced thermal performance.

The 88E1111-B2-NDC2I000 offers flexible MAC (Media Access Controller) interface options, including GMII (Gigabit Media Independent Interface), RGMII (Reduced GMII), SGMII (Serial GMII), TBI (Ten-Bit Interface), and RTBI (Reduced TBI), allowing seamless connection to a wide variety of host controllers and switches . It operates with a nominal core supply voltage of 1V and supports 2.5V for I/O, ensuring compatibility with modern low-power systems.

Key features include Auto-MDI/MDIX crossover detection, jumbo frame support up to 9KB, IEEE 1588 Precision Time Protocol (PTP) for precise timing synchronization, and integrated Digital Signal Processing (DSP) for enhanced signal integrity over long cables -9. The device is rated for the industrial temperature range of -40°C to +85°C, making it suitable for use in harsh environmental conditions. This device is RoHS compliant and lead-free. The 88E1111-B2-NDC2I000 is ideal for use in enterprise and carrier-grade networking equipment such as switches, routers, network interface cards (NICs), as well as in industrial automation, test instrumentation, and other embedded systems requiring reliable, high-speed wired connectivity.
