First switch enables port switching in next-generation LANs

Diodes Incorporated has introduced the PI3L2500 LAN multiplexer/demultiplexer, the industry's first switch designed to facilitate port switching in next-generation corporate LANs at Ethernet signal speeds of 2.5/5/10Gbps.


The device bidirectional mux/demux design allows two Ethernet PHY differential outputs to work with a single RJ45 connector or allows one Ethernet PHY output to be routed to one of two RJ45 connectors. This functionality gives the higher redundancy, flexibility, and performance required by device manufacturers wanting to add new equipment able to operate at today's LAN speeds while giving a migration path to higher speeds. Before the introduction of the device, LAN switches were only able to run up to 1Gbps.


Designed to offer a future-proof solution to high-speed signal routing, the device features a wide 2GHz signal bandwidth to carry data switching up to 10Gbps. The device delivers this performance using a 0.18μm process that produces extremely low on-resistance of 4Ohm and low on/off capacitance of just 1.5pF (on) and 3pF (off). To preserve signal fidelity, crosstalk and isolation are also extremely low at -35dB. High-speed operation also depends on low propagation, and the device provides this with a typical propagation delay of only 0.25ns.


"Diodes has been pioneering signal switches for over two decades, by being the first in market to address emerging technologies," said Kay Annamalai, senior marketing director, Diodes Incorporated. "The PI3L2500 2.5GE-10GE LAN switch will aid the migration within corporate networks from 1GE to 2.5GE Ethernet and beyond, for applications such as notebooks and docks, as well as in packet transport networks where upgradability and redundancy are needed."
