Product Description
Pericom Semiconductor's PI3L series of logic circuits are produced using the Company's advanced sub-micron CMOS technology, achieving industry leading performance. The PI3L301D is a 16- to 8-bit multiplexer/demultiplexer LAN Switch with Hi-Z outputs. Industry leading advantages include a propagation delay of less than 250ps, resulting from its low channel resistance and I/O capacitance. The device multiplexes differential outputs from a Gigabit Ethernet transceiver (PHY) device to one of two corresponding B1 or B2 outputs. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. It is designed for low bit-to-bit skew, high channel-to-channel noise isolation and is compatible with various standards, such as 10/100/1000 Base-T (Ethernet). Generally, this part can be used to replace mechanical relays in low-voltage LAN applications that interface a physical layer over CAT 5 or CAT 6 unshielded twisted pair cable through an isolation transformer.
Applications
· Dual Physical Layer Device sharing to one interface connector · SONET OC-12(622Mbps) signal routing · Routes physical layer signals for 10/100/1000 Mbit Ethernet
