8-PORT 10/100 SWITCH WITH ON-CHIP PACKET BUFFER

The Broadcom BCM5318device is a very highly integrated solution. It combines all the functions of a high-speed switch system–including packet buffer, PHY transceivers, media access controllers, address management and a non-blocking switch fabric–into a single 0.22µCMOS device. It complies with the IEEE 802.3, 802.3µand 802.3x specifications, including the MAC control PAUSE frame and auto-negotiation subsections, providing compatibility with all industry-standard Ethernet and Fast Ethernet devices.
