Datasheet

COO (Country of Origin):: TW

The KSZ8794CNX is a highly integrated, Layer 2 managed, four-port switch with numerous features designed to reduce system cost. It is intended for cost-sensitive applications requiring three 10/100Mbps copper ports and one 10/100/1000Mbps Gigabit uplink port. The KSZ8794CNX incorporates a small package outline, low power consumption with internal biasing, and on-chip termination

Integrated 4-port 10/100 Layer-2 switch with Gigabit uplink

New generation switch with three MACs, one GMAC (for uplink) and three PHYs

10/100Base-T/TX switch system which combines a switch engine, frame buffer management, address lookup table, queue management, MIB counters, MAC, and PHY transceivers

Rapid spanning tree support (RSTP) for topology management

Microchip's LinkMD® cable diagnostic capabilities for determining cable opens, shorts, and length

Advanced Switch Capabilities

VLAN support for up to 128 active VLAN groups (full range 4096 of VLAN IDs)
