Mux/demux from Diodes enables 10Gbps port switching

The bidirectional design enables two Ethernet PHY differential outputs to operate with a single RJ45 connector or enables one Ethernet PHY output to be routed to one of two RJ45 connectors.

The firm says this functionality provides redundancy, flexibility, and performance needed for today’s LAN speeds while providing a migration path to higher speeds.

The device can demultiplex one input port with eight channels to one of two output ports or multiplex two input ports to one output port.

Ports are selected using a SEL input and a power down (PD) input that sets the device to standby mode.

In active mode, the switch consumes a maximum active current of just 1.5mA (1.0mA typical) and a standby current of 0.3mA (typical).

Three multiplexed channels are also provided for switching status LEDs.

Designed for applications requiring high-speed signal routing, the PI3L2500 features a wide 2GHz signal bandwidth to carry data switching up to 10Gbps.

The device achieves this performance using a 0.18μm process that delivers on-resistance of 4Ω and on/off capacitance of 1.5pF (on) and 3.0pF (off).

Crosstalk and isolation values are at -35dB, and its propagation delay is 0.25ns.

Kay Annamalai, senior marketing director, Diodes says “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.”

The PI3L2500ZHEX is now available in the 42-pin TQFN package, priced at $1.25 each in 5000 piece quantities.
