Micrel Semiconductor,an industry leader in analog,high-bandwidth communications and Ethernet integrated circuit(IC)solutions,today released the KSZ8895/8875/8864 series of products.The device is a low-power,highly integrated 4/5-port 2-layer switch integrated circuit on a chip.This product series adopts Merrill Semiconductor's latest green physical transceiver and switch technology,which reduces power consumption by 50%compared with previous generation products.The power management and mature QoS performance of this series can meet the growing demand for Ethernet connections in consumer and industrial applications.Mass production of this series of products will begin in the first quarter of 2011,and product pricing and ordering samples are currently available.
Wiren Perera,Director of Ethernet Products at Mairui Semiconductors,said:"Digital homes have always used Ethernet to deliver content and connect media devices,which has driven the demand for high-port-count devices.Mairui Semiconductor’s new switch series directly meets these needs while achieving Energy efficiency requirements such as ENERGY STAR and other important green standards.This series of products are flexible in configuration and can meet various application requirements by relying on a single basic system platform."
QoS features,such as tag and port-based VLAN support and IPv6 priority classification,make these devices particularly suitable for the very demanding IP content applications in the current digital home:IPTV,IP-STB(set-top box),VoIP(voice over IP),Residential gateway and GPON.Low radiation and Micrel Semiconductor's unique high reliability and quality make these devices very suitable for connection applications in the rapidly growing industrial automation and automotive markets.
The device has a built-in 1.2VLDO,supports a single 3.3V power supply,and can choose 3.3V,2.5V or 1.8VI/O voltage.The power management(including the device's"energy detection and power saving"mode)supports stronger energy-saving performance.This mode is activated when the cable is not plugged in,and the"slow oscillation"mode is activated when the device is not working.
This product series can choose MII or RMII interface and main processor or PHY connection.Copper or fiber optic interfaces provide flexibility.The on-chip matching terminal and internal 50MHz RMII clock function further reduce the cost of raw materials and reduce the package size(64-pin QFN of KSZ8864RMN).
