PERICOM PI3L110L

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 . . . Human Body Model
• >350 MHz bandwidth (or data frequency)
• Packaging (Pb-free & Green available)
16-pin 150 mil wide plastic QSOP (Q)
16-pin 173 mil wide plastic TSSOP(L)
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
• Routes signals for 10/100 Mbit Ethernet

2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading.
3. Measured by the voltage drop between IN and YN pins at indicated current through the switch. On-Resistance is determined by the lower of the
voltages on the two (IN & YN) pins.

Notes:
1. 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.

Applications Information
Logic Inputs
The logic control inputs can be driven up to +3.6V regardless of the supply voltage. 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.
