BCM5328x Family数据手册Broadcom中文资料规格书

描述 Description

Tenth-generation RoboSwitch™ design based on the field-proven BCM53242/BCM53262 device. This integrated 65 nm CMOS device combines all the functions of a high-speed switch system including packet buffers, PHY transceivers, Media Access Controllers (MACs), address management and a nonblocking switch fabric. It is designed to be fully compliant with the IEEE 802.3™ and IEEE 802.3x specifications, including the MAC control Pause frame, auto-negotiation and all industry-standard Ethernet and Fast Ethernet devices. The BCM5328XM contains 8/16/24 full-duplex 10BASE-T/ 100BASE-TX Fast Ethernet transceivers. Each transceiver performs all physical layer interface functions for 10BASE-T Ethernet on Category 3, 4 or 5 Unshielded Twisted Pair (UTP) cable and 100BASE-TX Fast Ethernet on Category 5 UTP cable. The BCM5328XM has two GMII/ RGMII interfaces or four SGMII/SerDes (serializer/deserializer) interfaces or two SGMII/SerDes with 2.5G combo SerDes interface. An additional MAC is included for CPU connection using an interface. For documentation and support visit Broadcom Communities
