Quad-Port GbE Transceiver with IEEE1588v2 and IEEE 802.3az EEE Support
Product Code: BCM54640E
Based on the proven digital signal processor (DSP) 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 monolithic CMOS chip.
The BCM54640E transceiver can support either four SGMII-to-copper (10/100/1000BASE-T) interfaces or four SGMII-to-Fiber (100BASE-FX, 1000BASE-X or SGMII-Slave) interfaces. When in SGMII-to-Copper mode, the PHY performs all of the physical layer functions for 1000BASE-T, 100BASE-TX and 10BASE-T on standard Category 5 unshielded twisted-pair cable. When in SGMII-to-Fiber mode, the PHY performs all of the physical layer functions for 100BASE-FX, 1000BASE-X and SGMII-Slave. The BCM54640E is designed to comply with the SGMII industry standard. With full compliance to IEEE 802.3az Energy Efficient Ethernet standard, the BCM54640E substantially lowers power consumption during periods of low-link utilization. In addition, with Broadcom's AutogrEEEn® technology, the BCM54640E 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. For applications that require precise and accurate synchronization of nodes in the network, the BCM54640E includes support for 1588 Precision Time Protocol (PTP) and is fully compliant to IEEE 1588-2008 (version 2) standard.
Supports four copper ports (10BASE-T/100BASE-TX/1000BASE-T) or four fiber ports (100BASE-FX/1000BASE-X) in a single fully integrated 65 nm CMOS chip
