DP83016AUG - Falcon Switch
16-port Gigabit Ethernet Switch Engine
General Description
Features
The DP83016 (Falcon switch) is a wirespeed, full featured — 16 10/100/1000 Mb/s Ethernet ports with non-blocking
16-port Gigabit Ethernet Switch-On-a-Chip with several
integrated management interfaces, which supports both,
copper and optical PHYs.
wire-speed performance
— 32 Gbit/s internal switching bandwidth, 24 Mpps for-
warding rate
The DP83016 provides non-blocking, wire-speed Gigabit
performance on all ports and supports both managed and
unmanaged operation.
— MII / GMII / RGMII operation for copper PHYs, TBI /
RTBI interface for fiber / SerDes
— 4-wire serial CPU interface for low cost unmanaged sys-
tems
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.
— 16-bit CPU interface for SNMP and Web based man-
agement
— 256 kB on-chip frame buffer
— Programmable classifier for QoS (Layer-4/Multi-media)
— 4k VLAN (IEEE802.1Q) and 4k MAC address support
An on-chip 256kB frame buffer allows for an extremely
simple system design.
— Full duplex flow control (IEEE802.3x) and half duplex
back pressure
Using only two DP83016 devices, 24-port Gigabit Switch
designs are possible.
— Flexible link aggregation based on IEEE802.3ad
The DP83016 forwards frames at layer 2 based on informa-
tion from layer 2 through layer 4. It supports programmable — Spanning Tree Protocol support (IEEE802.1D)
classification and prioritization to enable enhanced Quality
— GARP, GMRP and GVRP support
of Service (QoS) support for real time applications such as
— IGMP Snooping supported
Voice-over-IP (VoIP).
— Extended statistics for RMON IEEE 802.3z TBI
— JTAG (IEEE 1149,1-1994) support
