RON is 4Ω typical Low bit-to-bit skew: 200ps Low crosstalk: –27dB @ 250MHz Low Current Consumption: 20µA Near-Zero propagation delay: 250ps Switching speed: 9ns Channel On-Capacitance: 9.5pF (typical) VCC Operating Range: +3.0V to +3.6V ESD >3000V . . . Human Body Model >350 MHz bandwidth (or data frequency) Packaging (Pb-free & Green available): 48-pin 240 mil wide plastic TSSOP (A) 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 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 Pin Description Block Diagram A0 0B1 A1 1B1 0B2 1B2 A2 2B1 A3 3B1 3B2 A4 4B1 A5 5B1 1 48 A0 2 47 1B1 GND 3 46 GND A1 4 45 0B2 GND 5 44 1B2 GND V DD 6 43 GND 7 42 2B1 A2 8 41 3B1 GND 2B2 4B2 5B2 0B1 V DD 9 40 GND A3 10 11 39 38 2B2 GND 3B2 V DD 12 37 GND GND 13 36 V DD NC 14 35 4B1 A4 15 34 5B1 GND 16 33 GND A5 17 32 GND 4B2 18 31 5B2 GND A6 6B1 V DD 19 30 A7 7B1 GND 20 29 A6 6B1 21 28 GND 7B1 22 27 A7 GND 23 24 26 6B2 6B2 7B2 SEL SEL 13-0142 1 25 7B2 www.pericom.com PS8162F 05/08/13 PI3L301D 3.3V, 16-Bit to 8-Bit, Mux/DeMux Gigabit Ethernet LAN Switch with Single Enable Maximum Ratings Truth Table (Above which useful life may be impaired.

Typical valves are at Vcc = 3.3V, Ta = 25°C ambient and maximum loading. 3. 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. 4.

For example, given a +3.3V supply, the output enables or select pins may be driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail® minimizes power consumption. Power-Supply Sequencing Proper power-supply sequencing is advised for all CMOS devices. It is recommended to always apply VCC before applying signals to the input/output or control pins.
