KSZ8993 Description

Short technical summary and product information.

The KSZ8993 from Micrel Inc. is a versatile 3-port 10/100 integrated switch IC designed for network applications. It combines three physical layer transceivers and three MAC units with an integrated Layer 2 switch. The device supports two modes of operation: a standard three-port integrated switch or a three-port switch with the third port decoupled for external MAC connectivity via MII or SNI interfaces.

Key features include 1Gbps high-performance memory bandwidth and 64k Bytes of on-chip SRAM for frame buffering. It supports 10BaseT, 100BaseTX, and 100BaseFX network standards, making it suitable for both UTP and fiber installations. The KSZ8993 operates in an unmanaged mode, configured via I/O strapping at system reset, simplifying integration.

This IC supports advanced features such as port-based VLAN and 802.1p priority queuing for Quality of Service (QoS). It also includes hardware-based auto-negotiation, flow control, and individual port forced modes. Indicators for link, activity, duplex, and speed are provided. The device is housed in a 128-Pin PQFP package.
