Micrel Inc. has launched the KSZ8873MLL AM three-port switch on a chip IC, with low power dissipation, efficient power management and sophisticated QoS features. The highly-integrated solution is qualified for AEC-Q100 and as such, enables automotive manufacturers to use Ethernet as the backbone for their next-generation automotive multimedia networks.

"As Ethernet significantly reduces the cost of ownership in the automobile, the global automotive community is quickly embracing Ethernet as the defacto network platform in a car," noted J.C. Lin, Micrel's VP of Ethernet products. "Micrel, known for the highest quality and reliability products, is the first vendor to offer Ethernet ICs for automotive diagnostics and software download. This new switch product, with its low power and small footprint, offers customers the ideal solution to build the Ethernet backbone for the multimedia network in the next generation of vehicles."

Micrel's AEC-Q100-qualified (for automotive applications) device offers low power consumption and advanced power management schemes that accommodate "green" system design requirements. The KSZ8873MLL AM's small package size (64-pin LQFP) and high integration (on-chip LDO) reduce system cost and simplify system design. In addition, the Port 1 and Port 2 by-pass mode allows the device connected to the MII interface so it can enter a power saving mode without impacting the normal switch operation. Enhanced QoS support (4-queue traffic prioritization and source address filtering) facilitates implementation of advanced QoS policies in the Ethernet ring network for automotive applications. Finally, the chip features source address filtering, rate limiting per queue and Auto-MDI/MDIX that eliminates the need for cross-over cable, thus reduces installation costs.
