KSZ8842-32MQL Datasheet
Product Details
General Description
The KSZ8842-series of 2-port switches includes PCI and non-PCI CPU
interfaces, and are available in 8/16-bit and 32-bit bus designs
(see Ordering Information). This datasheet describes the
KSZ8842M-series of non-PCI CPU interface chips. For information on
the KSZ8842 PCI CPU interface switches, refer to the KSZ8842P
datasheet.
Features
Switch Management
• Non-blocking switch fabric assures fast packet delivery by
utilizing a 1K entry forwarding table
• 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
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
• Per port-based, software power-save on PHY (idle link detection,
register configuration preserved)
• Single power supply: 3.3V
• Commercial Temperature Range: 0°C to +70°C
• Industrial Temperature Range: –40°C to +85°C (see Ordering
Information)
• Available in 128-pin PQFP and 100-ball LFBGA (optional package:
128-pin LQFP)
• 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 KSZ8842M offers:
• Repeater mode capabilities to allow for cut through in latency
critical industrial Ethernet or embedded Ethernet applications
• 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
