KSZ8842-16/32 MQL/MVL/MVLI 2-Port Ethernet Switch with Non-PCI Interface Data Sheet is the datasheet of the KSZ8842M series of non-PCI CPU interface chips. This chip is the industry's first fully managed, 2-port switch with a non-PCI CPU interface. It is based on a proven, fourth generation, integrated Layer-2 switch, compliant with IEEE 802.3u standards.
This datasheet describes the KSZ8842M-series of non-PCI CPU interface chips, which are 2-port switches compliant with IEEE 802.3u standards. The device supports VLAN, QoS, and MIB counters, and can operate in half-duplex mode for industrial applications. It includes features like IGMP snooping, port mirroring, and dynamic buffer memory for video over IP.
The switch is available in commercial and industrial temperature ranges, with options for 8/16-bit or 32-bit bus support, and comes in PQFP or LQFP packages. It also supports LinkMD cable diagnostics and auto-MDIX crossover for flexible connectivity.
