PI3L2500 MUX/DEMUX LAN Switch Diodes Incorporated PI3L2500 MUX/DEMUX LAN Switch is an 8-Channel 2:1 Mux/DeMux and 1:2 Gigabit LAN Switch with power-down mode. This switch features a propagation delay of less than 250ps and offers 200ps of low bit-to-bit skew. The PI3L2500 LAN switch multiplexes differential outputs from a Gigabit Ethernet transceiver (PHY) device to one of the B or C outputs. This switch is designed for high channel-to-channel noise isolation and is compatible with various standards such as 1000/2500/10000 Base-T (Ethernet). The PI3L2500 LAN switch provides a Power Down input (PD) that puts the device into standby mode (PD=1) and eliminates external power switch. This LAN switch is used for applications such as dual physical layer device sharing to one interface connector and routes signals for 1000/2500/10000 Mbit Ethernet.
