Micrel Supplies Integrated 5-Port 10/100 Managed Ethernet Switch with Gigabit Interface
On March 9, 2015, Micrel Korea (CEO Young-Jun Oh, www.micrel.com), an industry leader in LAN, timing, and communications solutions as well as high-performance linear and power solutions, announced the supply of the KSZ8765CLX device, a highly integrated Layer 2-managed, 5-port Ethernet switch designed to dramatically reduce overall system costs. Integrating various functions onto a single chip, this device was launched specifically for price-sensitive applications and supports four 10/100Mbps modem ports and one 10/100/1000Mbps Gigabit uplink port. The KSZ8765CLX device is supplied in a small 80-pin LQFP package, features very low power consumption, internal biasing, and on-chip termination.

Equipped with various features including advanced power management capabilities, this device includes programmable rate limits, priority ratios, tagged and port-based VLANs, port-based security and ACL rule-based packet filtering technology, QoS priority functions, as well as four queues, a management interface, enhanced MIB counters, high-performance memory bandwidth, and a shared memory-based switch fabric that supports non-blocking. In addition, the KSZ8765CLX supports a multi-CPU data interface to effectively handle both high-speed Ethernet and Gigabit Ethernet applications, which can be configured with any RGMII, MII, or RMII mode via the GMAC interface.
The KSZ8765CLX device is implemented based on Micrel's industry-leading, latest Ethernet analog and digital technologies and is designed to offload host processing and facilitate design execution. It features two integrated MAC/PHYs 100Base-FX on Ports 1 and 2, and two integrated MAC/PHYs 10/100Base-T/TX on Ports 3 and 4, and is provided with a single integrated 10/100/1000Base-T/TX GMAC with selectable GMII, RGMII, MII, and RMII interfaces.
Equipped with excellent power management functions such as Energy-Efficient Ethernet (EEE), Power Management Event (PME), and Wake-on-LAN (WoL), the KSZ8765CLX is highly suitable for environments requiring high energy efficiency. All registers of the MAC/PHY unit can be managed via the SPI interface, and MIIM PHY registers can be accessed via the MDC/MDIO interface. Key application areas are diverse, including industrial Ethernet and VoIP based on IEEE 802.3-compliant MACs, set-top boxes, industrial control, automotive, IPTV POF, broadband gateways and firewalls/VPNs, integrated DSL/cable modems, wireless LAN access points/gateways, and network-based measurement and control systems.
