Growing demand for network bandwidth is one of the biggest pain points in data centers, and the data center is moving from 10G to 25G Ethernet to meet the growing demand for bandwidth. To achieve this goal, IEEE developed the 802.3by standard, a detailed definition of 25G Ethernet specifications, and in the recent approval. The high-performance Marvell Alaska C 88X5123 Ethernet transceiver is the industry’s first fully compliant PHY transceiver with the new IEEE 25G Ethernet standard.

The availability of standard-compliant devices is critical for a wide range of 25G Ethernet applications. “By delivering the industry’s first fully compliant PHY devices with IEEE 802.3by 25G Ethernet standards, our customers are able to develop products and applications that meet the new standards and thus have a place in the 25G Ethernet market.” 36tmh01

In addition to supporting the IEEE 802.3by 25G Ethernet standard, the 88X5123 is compatible with the IEEE 802.3bj 100G Ethernet standard and the 25 / 50G Ethernet Consortium standard. The package size is 17mm x 17mm and supports eight 25G Ethernet ports, four 50G Ethernet ports, or two 100G Ethernet ports. It also supports high-density 40G Ethernet solutions with gearboxing support, Local 25G I / O replaces the ASIC. ucb1400be

The 88X5123 supports long-reach SerDes and incorporates forward error correction capability to support a wide range of media types, including single-mode and multimode optical modules, passive and active direct-connect copper, and copper backplanes. The device has a fully symmetrical architecture, the host side and line side have long-range SerDes and forward error correction capability, providing flexibility for the customer’s system design.
