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