Five-Port Ethernet Switch Targets Cost-Sensitive Low-Port Apps

The KSZ8995FQ five-port Ethernet switch from Micrel targets applications with low port counts like industrial Ethernet, managed media converters, and fiber to the premises (FTTP) customer premise equipment (CPE) where low bill of materials (BOM) costs are essential. It includes five full 10/100-Mbit/s transceivers, five media access control (MAC) units, a high-speed non-blocking switch fabric, a dedicated address lookup engine, and an on-chip frame buffer memory.

The KSZ8995FQâ??s ports support the usual 10BaseT and 100BaseTX 802.3 standards. Two of the ports also handle 100BaseFX, which is the fiber version. Designers can use the chip to build loop applications using two fiber ports to cascade a ring while using the media independent interface (MII) on another port to the CPU/host.
