Microchip | KSZ8842-16MVLI

The KSZ8842-16MVLI is a part of KSZ8842-series of 2-port switches includes PCI and non-PCI CPU interfaces, and are available in 8/16-bit and 32-bit bus designs The KSZ8842M is the industry’s first fully managed, 2-port switch with a non-PCI CPU interface.

It is based on a proven, 4th generation, integrated Layer-2 switch, compliant with IEEE 802.3u standards.The KSZ8842M can be configured as a switch or as a low-latency (≤ 310 nanoseconds) repeater in latency-critical, embedded or industrial Ethernet applications.
