DP83016AUG - Falcon Switch
16-port Gigabit Ethernet Switch Engine
General Description
Features
The DP83016 (Falcon switch) is a wirespeed, full featured
16-port Gigabit Ethernet Switch-On-a-Chip with several
integrated management interfaces, which supports both,
copper and optical PHYs.
The DP83016 provides non-blocking, wire-speed Gigabit
performance on all ports and supports both managed and
unmanaged operation.
The DP83016 minimizes total system cost. It offers the
most cost effective 16 port Gigabit switch solution in the
market by removing the need for external memory. Further-
more, it eliminates the requirement for a configuration
EEPROM.
An on-chip 256kB frame buffer allows for an extremely
simple system design.
Using only two DP83016 devices, 24-port Gigabit Switch
designs are possible.
The DP83016 forwards frames at layer 2 based on informa-
tion from layer 2 through layer 4. It supports programmable
classification and prioritization to enable enhanced Quality
of Service (QoS) support for real time applications such as
Voice-over-IP (VoIP).
