Versatile 2-port Ethernet Device with Added Benefits
Replacing two devices with a single cost-effective, flexible solution, the Micrel KS8842M from Solid Sate Supplies is the industry’s first 2-port Ethernet device, with a third port that can be connected directly to microprocessors through a generic 8-or 16-bit bus interface.Aime
The KS8842M can be configured as a fully managed Layer-2 switch with the third port connected to a host processor, or it can be configured as a repeater for use in latency-critical applications in industrial Ethernet where all packets from one port are broadcast to the remaining two ports, bypassing the lookup tables used in a typical store-and-forward switch architecture. The device may also be used to replace two single Ethernet controllers with a single KS8842M IC where network traffic is 100% segregated between the two ports.
Auto-MDIXs, a standard feature in all Micrel’s Ethernet devices, enables straight or crossover cables to be connected to the device, taking the guesswork away for the end user. The device also features Link Doctor (LinkMD?), a cable diagnostic package that enables diagnosis of common cabling problems resulting in reduced customer calls and IT service requests.
