KSZ8993M数据手册集成电路（IC）的专用IC规格书PDF

描述 Description

General Description
The KSZ8993M, a highly integrated Layer 2 managed switch, is designed for low port count, cost-sensitive 10/100 Mbps switch systems. It offers an extensive feature set that includes tag/port-based VLAN, quality of service (QoS) priority, management, management information base (MIB) counters, MII/SNI, and CPU control/data interfaces to effectively address both current and emerging Fast Ethernet applications.

特性 Features

• Proven Integrated 3-Port 10/100 Ethernet Switch
– 2nd generation switch with three MACs and two PHYs fully compliant to IEEE 802.3u standard
– Non-blocking switch fabric assures fast packet delivery by utilizing a 1K MAC address lookup table and a store-and-forward architecture
– Full duplex IEEE 802.3x flow control (pause) with force mode option
– Half-duplex back pressure flow control
– Automatic MDI/MDI-X crossover with disable and enable option
– 100BASE-FX support on port 1
– MII interface supports both MAC mode and PHY mode
– 7-wire serial network interface (SNI) support for legacy MAC
– Comprehensive LED Indicator support for link, activity, full/half duplex and 10/100 speed
• Comprehensive Configuration Register Access
– Serial management interface (SMI) to all internal registers
– MII management (MIIM) interface to PHY registers
– 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…)
