KSZ8862MQL Datasheet, PDF (2/125 Pages) Micrel Semiconductor – 2-Port Ethernet Switch with Non-PCI Interface and Fiber Support

Micrel, Inc.
Features
Switch Management
• Non-blocking switch fabric assures fast packet
delivery by utilizing a 1K entry forwarding table and a
store-and-forward architecture
• Fully compliant with IEEE 802.3u standards
• Full-duplex IEEE 802.3x flow control (Pause) with
force mode option
• Half-duplex back pressure flow control
Advanced Switch Management
• IEEE 802.1Q VLAN support for up to 16 groups (full
range of VLAN IDs)
• VLAN ID tag/untag options, on a per port basis
• IEEE 802.1p/Q tag insertion or removal on a per port
basis (egress)
• Programmable rate limiting at the ingress and egress
ports
• Broadcast storm protection
• IEEE 802.1d spanning tree protocol support
• MAC filtering function to filter or forward unknown
unicast packets
• Direct forwarding mode enabling the processor to
identify the ingress port and to specify the egress port
• Internet Group Management Protocol (IGMP) v1/v2
snooping support for multicast packet filtering
• IPV6 Multicast Listener Discovery (MLD) snooping
support
Fiber Support
• Integrated LED driver and post amplifier for 10BASE-
FL and 100BASE-SX optical modules
• 100BASE-FX/SX and 10BASE-FL fiber support on
port 1
Monitoring
• Port mirroring/monitoring/sniffing: ingress and/or
egress traffic to any port
• MIB counters for fully compliant statistics gathering –
34 MIB counters per port
• Loopback modes for remote failure diagnostics
Comprehensive Register Access
• Control registers configurable on-the-fly (port-priority,
802.1p/d/Q)
QoS/CoS Packets Prioritization Support
• Per port, 802.1p and DiffServ-based
• Remapping of 802.1p priority field on a per port basis
Power Modes, Packaging, and Power Supplies
• Full-chip hardware power-down (register configuration
not saved) allows low power dissipation
KSZ8862-16/32MQL
• Per port-based, software power-save on PHY (idle
link detection, register configuration preserved)
• Single power supply: 3.3V
• Commercial Temperature Range: 0oC to +70oC
• Industrial Temperature Range: –40oC to +85oC
(see Ordering Information).
• Available in 128-pin PQFP
• Available in –16 version for 8/16-bit bus support and –
32 version for 32-bit bus support (see Ordering
Information).
Additional Features
In addition to offering all of the features of an integrated
Layer-2 managed switch, the KSZ8862M offers:
• Dynamic buffer memory scheme
– Essential for applications such as Video over IP
where image jitter is unacceptable
• 2-port switch with a flexible 8, 16, or 32-bit generic
host processor interfaces
• Micrel LinkMD^® cable diagnostics to determine cable
length, diagnose faulty cables, and determine
distance-to-fault
• Hewlett Packard (HP) Auto-MDIX crossover with
disable and enable options
• Four priority queues to handle voice, video, data, and
control packets
• Ability to transmit and receive jumbo frame sizes up to
1916 bytes
Applications
• Video Distribution Systems
• High-end Cable, Satellite, and IP set-top boxes
• Video over IP
• Voice over IP (VoIP) and Analog Telephone Adapters
(ATA)
• Industrial Control in Latency Critical Applications
• Motion Control
• Industrial Control Sensor Devices (Temperature,
Pressure, Levels, and Valves)
• Security and Surveillance Cameras
Markets
• Fast Ethernet
• Embedded Ethernet
• Industrial Ethernet
