Integrated 3-Port 10/100 Managed Switch with PHYs

Micrel 

Micrel, Inc.

Features

• Advanced Switch Features

- IEEE 802.1q VLAN support for up to 16 groups

(full-range of VLAN IDs)

- VLAN ID tag/untag options, 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 on a per port basis

- Broadcast storm protection with % control

(global and per port basis)

- IEEE 802.1d rapid spanning tree protocol

support

- tail tag mode (1 byte added before FCS) support

at port3 to inform the processor which ingress

port receives the packet and its priority

- Bypass feature which Automatically sustains the

switch function between Port1 and Port2 when

CPU (Port 3 interface) goes to the sleep mode

- Self-address filtering

- Individual MAC address for port1 and port2

- Support RMII interface and 50 MHz reference

clock output

- IGMP snooping (Ipv4) support for multicast

packet Filtering

- IPv4/IPv6 QoS support.

- MAC filtering function to forward unknown

unicast packets to specified port

• Comprehensive Configuration Register Access

- Serial management interface (SMI) to all internal

registers

- MII management (MIIM) interface to PHY

registers

- High speed SPI and I2C Interface to all internal

registers

- I/0 pins strapping and EEPROM to program

selective registers in unmanaged switch mode

- Control registers configurable on the fly (port-

priority, 802.1p/d/q, AN…)

• QoS/CoS Packet Prioritization Support

- Per port, 802.1p and DiffServ-based

- Re-mapping of 802.1p priority field per port

basis Four priority levels

• Proven Integrated 3-Port 10/100 Ethernet Switch

- 3rd generation switch with three MACs and two

PHYs fully compliant with IEEE 802.3u standard

- Non-blocking switch fabric assures fast packet

delivery by utilizing an 1K MAC address lookup

table and a store-and-forward architecture

KSZ8863MLL/FLL//RLL

- Full duplex IEEE 802.3x flow control (PAUSE)

with force mode option

- Half-duplex back pressure flow control

- HP Auto MDI-X for reliable detection of and

correction for straight-through and crossover

cables with disable and enable option

- Micre LinkMD® TDR-based cable diagnostics

permit identification of faulty copper cabling

- MII interface supports both MAC mode and PHY

mode

- Comprehensive LED Indicator support for link,

activity, full/half duplex and 10/100 speed

- HBM ESD Rating 4kV

• Switch Monitoring Features

- Port mirroring/monitoring/sniffing: ingress and/or

egress traffic to any port or MII

- MIB counters for fully compliant statistics

gathering 34 MIB counters per port

- Loopback modes for remote diagnostic of failure

• Low Power Dissipation

- Full-chip software power-down (register

configuration not saved)

- Energy-detect mode support

- Dynamic clock tree shutdown feature

- Per port based software power-save on PHY

(idle link detection, register configuration

preserved)

- Voltages: Single 3.3V supply with internal 1.8V

LDO for 3.3V VDDIO

- Optional 3.3V, 2.5V and 1.8V for VDDIO

- Transceiver power 3.3V for VDDA_3.3

• Industrial Temperature Range: –40oC to +85oC

• Available in 48-Pin LQFP, Lead-free package
