BCM53212数据手册集成电路（IC）的控制器规格书PDF

描述 Description

Ninth-generation RoboSwitch™ design based on the field-proven BCM5320 device. This integrated 0.13-micron 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 non-blocking 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 with all industry standard Ethernet and Fast Ethernet devices. The BCM53212M contains 16 full-duplex 10BASE-T/100BASE-TX Fast Ethernet transceivers with advanced cable diagnostics support. Each performs all of the 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. In addition, the BCM53212M has two GMII/RGMII/TBI interfaces that provide flexible 10/100/1000BASE-TX/FX connectivity. An additional MAC is included for CPU connection via RvMII or MII interface.
