• Description: USB2.0 to 10/100M Fast Ethernet Controller
• Manufacturer: DAVICOM [Davicom Semiconductor, Inc.]

1.1 System Description
The DM9620 USB to 10/100Mbps Fast Ethernet controller is a high performance and highly
integrated ASIC with embedded SSRAM for packet buffering. It enables low cost and
affordable Fast Ethernet network connection to desktop, notebook PC, and embedded
system using popular USB ports.
It has an USB interface to communicate with USB host controller and is compliant with USB
specification V1.0, V1.1 and V2.0. It implements 10/100Mbps Ethernet LAN function based on
IEEE802.3, and IEEE802.3u standards.
DM9620 integrates an on-chip 10/100Mbps Ethernet PHY to simplify system design and
provides an optional media-independent interface (MII/Reverse MII/RMII).
