The STMUX1000L is an 8- to 16-bit bi-directional Multiplexer/Demultiplexer designed for applications that require signal routing at 10/100/1000 Megabit Ethernet speeds. It integrates three Single Pole Dual Throw (SPDT) Channels for LED support and is available in two different packages, the TSSOP56 and QFN56. This application note highlights various applications into which the STMUX1000L Gigabit LAN Switch can be designed, such as PC Notebooks and docking stations. These are applications where several electrical characteristics impact high performance data transfer, including low noise between signals, low RON, and low Con and Coff capacitance. Additionally, the superior performance of the STMUX1000L is illustrated when compared to a competitor's device.
