Data Sheet BCM5387 Single-Chip 5-Port SerDes Gigabit Switch GENERAL DESCRIPTION FEATURES The BCM5387 is a 5-port gigabit switch integrated 5-port 10/100/1000 Mbps integrated switch with five 1.25 Gbps SerDes/SGMII port interfaces for controller via 1.25 Gbps SerDes/SGMII/Fiber connecting to external gigabit PHYs or fiber modules. Embedded 128 KB on-chip packet buffer The BCM5387 provides the lowest-cost Gigabit One 1000/100/10 Mbps inband management Ethernet-to-the-desktop switching solution or port (IMP) with a GMII/RGMII/RvMII interface WebSmart application. for PHY-less connection to a CPU/management entity The BCM5387 is a highly integrated solution, Integrated address management combining all the functions of a high-speed switch system, including packet buffer, media access Supports up to 4000 unicast addresses controllers (MACs), address management, and a non- Supports jumbo frame up to 9728 bytes blocking switch controller into a single monolithic Supports EEPROM for low-cost chip configuration 0.13-m CMOS device. The BCM5387 complies with Integrated Motorola SPI-compatible interface the IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE Port-mirroring support 802.3x specifications, including the MAC control Port-based VLAN and 4K IEEE 802.1Q tag VLAN PAUSE frame and auto-negotiation subsections, providing compatibility with all industry-standard Port, DiffServ, weighted/strict priority, and IEEE Ethernet, Fast Ethernet, and Gigabit Ethernet 802.1p-based QoS for four queues devices. Spanning tree support MAC-based trunking with link failover The BCM5387 provides integrated 1.25 Gbps SerDes, reducing board footprint requirements. The five Low-power (1.0W total , 1.2V core , and 2.5V ports have SGMII interfaces for connecting with RGMII , or 3.3V GMII/MII ) with 3.3V I/O external Gigabit transceivers. tolerance 256-FBGA Switch Controller SerDes Deserializer Gigabit Interface Serializer MAC Internal Port 0 Quality of Service Regulators (QoS) SerDes Gigabit Deserializer Interface Serializer MAC Port 1 MDIO/MDC Interface VLAN SerDes Gigabit Register Deserializer Configuration Interface Pins Serializer MAC Space Port 2 Jumbo Frames SPI Interface or EEPROM Interface SerDes Gigabit Deserializer Interface Serializer MAC Port 3 Port Trunking Memory SerDes Deserializer Gigabit Interface Serializer MAC Port 4 Rate Control Address GMII, Gigabit RvMII, or Management RGMII MAC Management Port Mirroring Figure 1: Functional Block Diagram 5387-DS10-R 5300 California Avenue Irvine, CA 92617 Phone: 949-926-5000 Fax: 949-926-5203 June 09, 2010 Broadcom ConfidentialBCM5387 Data Sheet Revision History Revision History Revision Date Change Description 5387-DS10-R 06/09/10 Added: Serial Interface Input Timing on page 191 Updated: Table 143: MAC Trunk Control Register (Page 032h, Address 01h), on page 167 5387-DS09-R 01/12/09 Updated: Ordering Information on page 168 5387-DS07-R 7/16/07 Updated: Port Trunking/Aggregation on page 7 Table 141, Trunk Group Register (Page 032h, Address 090h091h), on page 132 5387-DS06-R 2/28/07 Programming the VLAN Table on page 6 Table 13 on page 24 Table 124 on page 124 5387-DS05-R 10/18/06 Updated: Low-power voltage value in cover page Features bullet. 5387-DS04-R 10/09/06 Updated: Transmit Output Port Queues on page 37 Table 101, MII Status Register (Page 010h-017h: Address 02h-03h), on page 117 Table 106, SerDes/SGMII Control 1 Register (Page 010h-017h: Address 020h-021h), on page 121 Table 107, Analog Transmit Register (Page 010h-017h: Address 020h- 021h, Block 1), on page 123 Table 108, SerDes/SGMII Control 2 Register (Page 010h-017h: Address 022h-023h), on page 123 Table 167, Electrical Characteristics, on page 165 5387-DS03-R 03/23/06 Updated: Table 99, Internal Serial Port Registers (Page 010h017h), on page 115.
