BCM54880E

Octal-Port 1000/100/10BASE-T GbE Transceiver with IEEE1588v2 and IEEE802.3az EEE Support

The BCM54880E comprises eight complete 10/100/1000BASE-T Gigabit Ethernet transceivers, integrated on a single monolithic CMOS chip. The BCM54880E enables deployment of a new class of cost-effective and higher density switches for enterprise and data center applications. The BCM54880E is designed to comply with the SGMII industry standard and to exceed IEEE specifications for noise cancellation and transmission jitter, providing consistent and reliable operation over the broadest range of existing cable plants.

The BCM54880E is based on the proven digital signal processor technology of Broadcom, combining digital adaptive equalizers, ADCs, phase locked loops, line drivers, encoders, decoders, echo cancellers, crosstalk cancellers, and all other required support circuitry integrated into a single chip. With full compliance to IEEE 802.3az Energy Efficient Ethernet standard, the BCM54880E substantially lower power consumption during periods of low-link utilization. In addition, with Broadcom's AutogrEEEn™ technology, the BCM54880E can be in EEE mode when interfacing with non-EEE enabled MAC switches, allowing system designers to take advantage of EEE technology and realize power savings today. This power savings translates to lower energy costs for organizations that deploy networking equipment using the BCM54880E with EEE and AutogrEEEn technology. For application that require precise and accurate synchronization of nodes in the network, the BCM54880E includes support for 1588 Precision Time Protocol (PTP) and is fully compliant to IEEE 1588-2008(version 2) standard.
