Running Title—Attribute Reference Chapter 1 ThunderLAN Overview The ThunderLAN family consists of highly integrated, single-chip networking hardware. It uses a high-speed architecture that provides a complete peripher- al component interconnect (PCI)- to-10Base-T/AUI (adapter unit interface) Ethernet solution. It allows the flexibility to handle 100M-bps Ethernet proto- cols as the user’s networking requirements change. The TNETE100A, one implementation of the ThunderLAN architecture, is an int

ThunderLAN Architecture 1.1 ThunderLAN Architecture Figure 1–1. The ThunderLAN Controller LAN FIFO registers PHY 802.3 PCI LAN PCI Bus controller controller Multiplexed SRAM 100M-bps MII An integrated PHY provides interface functions for 10Base-T carrier sense multiple access/collision detect (CSMA/CD) (Ethernet). A MII is used to com- municate with the integrated PHY. The PHY is an independent module from the rest of the ThunderLAN controller. This allows the PHY to be reset and placed in a pow

Networking Protocols 1.2 Networking Protocols The MII also allows freedom in choosing a networking protocol. It allows the use of standard 100M bps CSMA/CD PHY chips. ThunderLAN uses these sig- nal lines to interface to an external 100M bps demand priority PHY. This gives ThunderLAN the flexibility necessary to handle 10Base-T, 10Base-2, 10Base-5 AUI, 100Base-TX, 100Base-T4, 100Base-FX, and 100VG-AnyLAN today, while supporting emerging technologies. ThunderLAN is designed to simplify the softwa
