PI3L110 3.3V Quad, 2:1 Mux/DeMux Fast Ethernet LAN Switch w/ Single Enable Features Description • RON is 4Ωs typical Pericom Semiconductor’s PI3L series of logic circuits are produced using the Company’s advanced sub-micron CMOS technology, achieving industry leading performance. • Low crosstalk: –27dB @ 250MHz • Near-Zero propagation delay: 250ps The PI3L110 is a 8- to 4-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 Fast Ethernet transceiver (PHY) device to one of two corresponding 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 Base-T (Ethernet). • Switching speed: 9ns • Channel On capacitance: 9pF (typical) • VCC Operating Range: +3.0V to +3.6V • ESD>2000V . . .

The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 10pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interactions with the load on the driven side. 3 PS8690A 09/22/04 PI3L110 3.3V Quad, 2:1 Mux/DeMux Fast Ethernet LAN Switch w/ Single Enable Test Circuit for Electrical Characteristics(1) 6.0V VCC 200-ohm Pulse Generator VIN D.U.T VOUT 10pF CL RT 200-ohm Notes: 1.
