Marvell Link Street-88E6390X
11 Port Ethernet Switch with Eight 10/100/1000Mbps PHYs
and Two XAUI/RXAUI/2500Base-X Interfaces
The Marvell® Link Street®-88E6390X device is a single-chip, 11-Port Ethernet Switch with eight integrated 10/100/1000Mbps
Ethernet transceivers and two high speed SerDes interfaces supporting 10Gbps XAUI and RXAUI, 2500-BaseX, 1000Base-X, and
SGMII. The device also includes an integrated 200MHz microprocessor to enable smart or lightly managed switches without the
need of an external CPU.
The 88E6390X provides advanced Quality of Service (QoS) features with 8 egress queues. The high performance switch fabric
provides line rate switching on all ports simultaneously while providing advanced switch functionality. The device includes a 256
entry TCAM to enable flexible switch policing, including Access Control Lists (ACLs) and Policy Control Lists (PCLs). The
88E6390X also supports the latest IEEE 802.1 Audio Video Bridging (AVB) and Time Sensitive Networking (TSN) standards. These
new standards overcome the latency and bandwidth limitations of Ethernet to allow for the efficient transmission of real-time
content for home, commercial, and industrial applications. These devices use the AVB/TSN technologies to identify and reserve
the network resources for AVB/TSN traffic streams and supports precise isochronous streaming capability for reliable and quality
audio/video transmission over Ethernet for today’s real-time, high definition information and entertainment options. The AVB/TSN
protocols enable timing sensitive streams (such as digital video, audio, or industrial control traffic) to be sent over the Ethernet
network with low latency and robust QoS guarantees.

Marvell Link Street-88E6390X
•• High performance, non-blocking, 11-port Ethernet Switch
fabricated on 28nm process, integrating:
- Eight 10/100/1000Mbps PHYs with Advanced Virtual Cable
Tester (VCT) diagnostic features
- Two 10Gbps XAUI/RXAUI Interfaces
o 2.5Gbps/1Gbps also supported
- Packaged in 361-BGA (17x17mm)
•• Provides a complete Gigabit Ethernet switching solution for
SOHO and SMB 8 port switches and routers.
•• The 10Gbps interfaces provide non-blocking uplink to cascade to
higher port count 16 and 24 port switches
•• Energy Efficient Ethernet PHYs reduce power consumption while
VCT provides qualitative cable-plant diagnosis, lowering Opex
•• Integrated 200MHz microprocessor
- Includes 60Kbytes integrated memory
•• Enables managed switch designs with the addition of a low cost
•• Supports IEEE 1588v2 one-step PTP
•• Cut-through switch fabric for low latency applications
•• Synchronous Ethernet for 1000Base-T or 100Base-TX
•• Advanced timing features support clock synchronization and
reduced latency for time sensitive content
•• 256 Entry TCAM for Deep Packet Inspection
-Looks up to 48 or 96 bytes deep into a frame
•• Enables intelligent switching and policing of packets by looking
beyond Layer 2 packet information
•• Supports 802.1 Audio Video Bridging (AVB) and Time Sensitive
Networking (TSN) Standards
•• Provides the latency, bandwidth and Quality of Service guarantees required to deliver today’s multimedia entertainment and
information over the Ethernet network.
•• Quality of Service (QoS) support with 8 traffic classes
-QoS determined by 802.1p, port, Source or Destination MAC
address, 802.1Q VLAN ID, Frame Type (e.g., ARP, Ethertype,
etc.), IPv4 Type of Service (TOS), Differentiated Service
(DiffServ), or IPv6 Traffic Class
•• Best in Class QoS features enable prioritization of all types of
traffic (e.g. video, voice, data) to ensure efficient use of network
bandwidth. Provides guaranteed delivery of time-sensitive
Audio/Video content when used in conjunction with AVB/TSN
•• Advanced Features
-High performance switch fabric with support for up to 16K MAC
-Supports 10KByte Jumbo Frames
