DM9332EP Product Brief
10/100Mbps Ethernet Fiber/Twisted Pair Single Chip Media
Converter
March 2009 Rev.1.0
The DM9332 is a fully integrated and cost-effective 10/100Mbps Ethernet
Fiber/Twisted Pair Single Chip Media Converter with MII/RMII Interface.
This new product provides basic Layer-2 switch functions and advance IEEE
802.1Q VLAN, priority queuing scheme.
Besides the DM9332 Fiber converter is complies with IEEE802.3 standards,
and designed for convert data signal between 10/100 Base-TX and 100
Base-FX fast Ethernet.
Media converters are connected between Fiber cable and twisted cable
segments with network and also the simplest way to interconnect any
equipment’s 100BASE-TX / 10BASE-T to the 100BASE-FX interface network.
