PI3L110LE

A product Line of Diodes Incorporated PI3L110 3.3V Quad, 2:1 Mux/DeMux Fast Ethernet LAN Switch w/ Single Enable Features Description • RON is 4Ω typical 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). • Low crosstalk: –27dB @ 250 MHz • Near-Zero propagation delay: 250ps • Switching speed: 9ns • Channel On capacitance: 9pF (typical) • VCC Operating Range: +3.0V to +3.6V • >2kV ESD protection (human body model) • >350 MHz bandwidth (or data frequency) 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. • Switching on Data I/O Ports (0 to 5V) • IOFF supports Partial-Power-Down mode operation • Data and Control Inputs have Undershoot Clamp Diodes • Packaging (Pb-free & Green available) – 16-pin 150-mil wide plastic QSOP (Q) – 16-pin 173-mil wide plastic TSSOP (L) The PI3L110 is fully specified for partial-power-down applications using IOFF. The IOFF feature ensures that damaging current will not backflow thoughout the device when it is powered down. The device has isolation during Power Off. Applications • Dual Physical Layer Device sharing to one interface connector • Routes signals for 10/100 Mbit Ethernet Pin Configuration Block Diagram IA0 IA1 IB0 IB1 IC0 IC1 ID0 ID1 S 1 16 IA0 2 15 3 14 4 13 5 12 6 11 7 10 8 9 IA1 E YA IB0 S IB1 YB GND YA YB All trademarks are property of their respective owners.

For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Guaranteed by design. 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.
