KSZ8775CLX
Integrated 5–Port 10/100 Managed Ethernet
Switch with Port 4 RMII and Port 5 RGMII/MII/
RMII Interfaces
Features
• Management Capabilities
-The KSZ8775CLX includes all the functions
of a 10/100BASE-T/TX switch system, which
combines a switch engine, frame buffer
management, address look-up table, queue
management, MIB counters, media access
controllers (MAC), and PHY transceivers
-Non-blocking store-and-forward switch fabric
assures fast packet delivery by utilizing a
1024-entry forwarding table
-Port mirroring/monitoring/sniffing: ingress
and/or egress traffic to any port
-MIB counters for fully compliant statistics
gathering -36 counters per port
-Hardware support for port-based flush and
freeze command in MIB counter.
-Multiple loopback of remote, PHY, and MAC
modes support for the diagnostics
-Rapid spanning tree support (RSTP) for
topology management and ring/linear
recovery
• Robust PHY Ports
-Four integrated IEEE 802.3/802.3u-compliant
Ethernet transceivers supporting 10Base-T
and 100BASE-TX
-802.1az EEE supported
-On-chip termination resistors and internal
biasing for differential pairs to reduce power
-HP Auto MDI/MDI-X™ crossover support
eliminates the need to differentiate between
straight or crossover cables in applications
• MAC and GMAC Ports
-Four internal media access control (MAC1 to
MAC4) units and one internal Gigabit media
access control (GMAC5) unit
-RGMII, MII, or RMII interfaces support for the
Port 5 GMAC5 with uplink and RMII interface
for Port 4 MAC4
-2 kb jumbo packet support
-Tail tagging mode (one byte added before
FCS) support on Port 5 to inform the
processor which ingress port receives the
packet and its priority DS00002129C-page 1 -Supports reduced media independent interface (RMII) with 50 MHz reference clock output
-Supports media independent interface (MII)
in either PHY mode or MAC mode on Port 5
-LinkMD® cable diagnostic capabilities for
determining cable opens, shorts, and length
• Advanced Switch Capabilities
-Non-blocking store-and-forward switch fabric
assures fast packet delivery by utilizing a
1024-entry forwarding table
-64kb frame buffer RAM
-IEEE 802.1q VLAN support for up to 128
active VLAN groups (full-range 4096 of VLAN
IDs)
-IEEE 802.1p/q tag insertion or removal on a
per port basis (egress)
-VLAN ID tag/untag options on per port basis
-Fully compliant with IEEE 802.3/802.3u standards
-IEEE 802.3x full-duplex with force mode
option and half-duplex back-pressure collision flow control
-IEEE 802.1w rapid spanning tree protocol
support
-IGMP v1/v2/v3 snooping for multicast packet
filtering
-QoS/CoS packets prioritization support:
802.1p, DiffServ-based and re-mapping of
802.1p priority field per port basis on four
priority levels
-IPv4/IPv6 QoS support
-IPv6 multicast listener discovery (MLD)
snooping
-Programmable rate limiting at the ingress and
egress ports on a per port basis
-Jitter-free per-packet-based rate limiting
support
-Tail tagging mode (one byte added before
FCS) support on Port 5 to inform the processor which ingress port receives the packet
and its priority
-Broadcast storm protection with percentage
control (global and per port basis)  2015 Microchip Technology Inc.
