看了评分，修改积分。16口千兆交换机芯片BCM5396 Design Guidelines 设计指南，配合技术手册使用效果更佳，没有更多的资料了，收好不谢！

Single-Chip 16-Port SerDes Gigabit Switch 16-port 10/100/1000 Mbps integrated switch controller via 1.25G SerDes/SGMII/fiber • Embedded 256 KB on-chip packet buffer • One 10/100/1000 Mbps In-band Management Port (IMP) with GMII/RGMII/RvMII/MII interface for PHY-less connection to a CPU/management entity (for management purposes only) • Integrated address management • Supports up to 4K MAC addresses • Supports jumbo frames up to 9728 bytes. • Supports EEPROM for low-cost chip configuration • Integrated Motorola® SPI-compatible interface • Supports port mirroring • Port-based VLAN and 4K IEEE 802.1Q tag VLAN • Port-, DiffServ-, MAC-, and IEEE 802.1p-based QoS for four queues • Supports Spanning Tree, Rapid Spanning Tree, and Multiple Spanning Tree protocols (802.1D/1s/1w) • Supports IEEE Standard 802.1X port security • Supports pseudo-PHY MDIO access • MAC-based trunking with link fail-over • Ethernet-in-the-last-mile (EFM) support: OAM and P • Low-power (2.2W total) 1.2V core/2.5V (SGMII I/ O)/3.3V (GMII/MII/RvMII) and 2.5V RGMII operation with 3.3V I/O tolerance • 256-pin FBGA package

本文分享一下16口交换机的芯片方案-RTL8316E，纯硬件，无需EEPROM及单片机配置，这个方案是经过打板验证过的。
