Supports 8 10/100Mbps network connections
8 dedicated MII interfaces can support 100BASE-TX/T4/FX PHY interfaces
Port 7 and/or 8 can connect to bridge, switch or MAC type device optionally.
Up-to 8 repeater chips can be cascaded for large HUB application(old method)
Up-to 6 repeaters can be cascaded for vertical expansion(new feature)
Up-to 4 chips can be cascaded locally for horizontal expansion(new feature)
Support two application mode : single or cascade
Low latency design supports Class II repeater implementation with large port number
All ports can be separately isolated or partitioned in response to fault condition
Separate jabber and partition state machines for each port
Per-port LED display for Jabber, Partition, Activity. Global partition, RAM test fail and
collision, utilization (%) for 10/100Mbps presentation
Power on LED diagnosis. All the LED display will follow the “ON-OFF-ON-OFF-Normal”
operation procedure during/after power on reset
