538X_5396 AN105 R.pdf

包含BCM5387,BCM5389,BCM5396的硬件设计指南。包括引脚处理方式;pcb设计规则;电源设计等。 The BCM5396 and BCM5389 product families include highly-integrated Gigabit Ethernet (GbE) switch devices featuring varying port counts of fully-integrated 1000 Mbps SerDes/Serial Gigabit Media Independent Interface (SGMII). An additional management port is configurable to GMII, Reduced GMII (RGMII), or MII (RvMII). These products integrate packet buffer, media access controllers (MACs), address management, and nonblocking switch fabric into a single 0.13μ CMOS device running on 2.5V/1.2V power supplies. They are ideally suited for a variety of applications where port density and power economy are key design criteria. The following table describes the covered products along with the corresponding port counts. The following technical information refers to BCM538X/BCM5396, but is intended to generically represent any of the below products. Individual products are referred to when necessary due to differences between the products.
