Human Body Model • >350 MHz bandwidth (or data frequency) • Packaging (Pb-free & Green available): 48-pin 240 mil wide plastic TSSOP (A) 48-pin 173 mil wide plastic TVSOP (K) 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 Description PericomSemiconductor’s PI3Lseriesof logiccircuitsareproduced 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. 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 offerslittleornoattenuationofthehigh-speedsignalsattheoutputs. 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.
