General Description

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).
