A product Line of Diodes Incorporated PI3L720 2:1 Mux/DeMux Gigabit Ethernet LAN Switch with Power-down Mode Features Description • • • • • • • • • The PI3L720 is a 8-Channel 2:1 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 Gigabit Ethernet transceiver (PHY) device to one of two corresponding B or C 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-tochannel noise isolation and is compatible with various standards, such as 10/100/1000 Base-T (Ethernet). 1:2 Gigabit LAN Switch Power-down support Low bit-to-bit skew: 200ps Very Low Crosstalk: –75dB @ 250MHz Status Indicator LEDs Switched with Ethernet pairs VDD Operating Range: +3.0V to +3.6V Enhanced ESD Protection (on A, B, C, LED pins): – 8kV (contact)(1) – 1.0kV (machine model), 11kV (human body model) >650 MHz bandwidth Packaging: – 42-contact TQFN (3.5 x 9mm, 0.5 pitch) The PI3L720 provides a Power Down input (PD), which can put the device into standby mode (PD=1) while mobile, eliminating an external power switch. 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.

Typical values are at VDD = 3.3V, Ta = 25°C ambient and maximum loading. 3. Measured by the voltage drop between A and B pins at indicated current through the switch. ON resistance is determined by the lower of the voltages on the two (A & B) pins. 4. This parameter is determined by device characterization but is not production tested.

For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at VDD = 3.3V, Ta = 25°C ambient and maximum loading.. 3. Active power represents normal data communication. Standby power is when the device is enabled for operation but there is no LAN traffic (cable not connected). Power down current is the minimum power state used when not connected and mobile. 4. 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.

Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control. All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, ZO = 50-Ohm, tR ≤ 2.5ns, tF ≤ 2.5ns. 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 VDD before applying signals to the input/output or control pins.
