with Dual MII/RMII/Turbo MII
PRODUCT FEATURES
Datasheet
Highlights
 Up to 200Mbps via Turbo MII Interface
 2nd MII/RMII/Turbo MII interface allows connection to
an external MOCA, HomePNA, HomePlug,
cable/DSL modem module or 2nd SOC with speeds
up to 200Mbps
 High performance, full featured 3 port switch with
VLAN, QoS packet prioritization, Rate Limiting, IGMP
monitoring and management functions
 Serial management via I2C or SMI
 Unique Virtual PHY feature simplifies software
development by mimicking the multiple switch ports
as a single port PHY
Target Applications
 Cable, satellite, and IP set-top boxes
 Digital televisions
 Digital video recorders
 VoIP/Video phone systems
 Home gateways
