World’s most integrated 10/100 managed switch
Lowest cost solution for SOHO and entry-level
corporate applications
Smallest form factor (reduces board space by 50%)
Scalable architecture supports 4 to 12 port densities
Fifth port supports any external Ethernet MII
transceiver
Eliminates cost of external LED latches and drivers
Robust and field-proven Digi-
Φ
based 10/100
transceivers
Substantially simplifies board and system design
Integrated transceivers eliminate pin-intensive media
Independent Interface (MII)
Internal PLL generates all system clocks from a single
25 MHz source
Fully manageable with external CPU
Basic management statistics can be gathered and
reported with only a very low-cost microcontroller
