| Micrel, Inc.'s KSZ8051series is a low-power, small package 10/100 physical (PHY) layer transceiver that provides the MII interface or the RMII interface to transmit and receive data over standard CAT-5 unshielded twisted pair (UTP) cable or fiber.
This PHY device is based on an enhanced mix-signal design and 0.13µm CMOS technology, which enable a new level of features, low power consumption, and high performance in a very compact package. It is the ideal choice for adding power-efficient 10/100 Ethernet connectivity to digital TVs, IP set-top boxes, game consoles, and industrial and automotive applications.
On-chip termination resistors and an integrated regulator simplify board layout while reducing the system BOM. The digital I/O interface supports 1.8V, 2.5V, and 3.3V voltage levels, offering flexibility in design. A suite of power-down and power-saving modes helps reduce power in various operating conditions further. This PHY device also provides patented techniques for lower EMI.
