3.3V, Wide Bandwidth, 1-Channel, 2:1 Mux/
DeMux Video Switch w/ Single Enable
Features
Description
• RON is 4Ω typical
Pericom Semiconductor’s PI3DBV series of logic circuits are
produced using the Company’s advanced sub-micron CMOS
technology, achieving industry leading performance.
• Low bit-to-bit skew: 200ps
• Low Crosstalk: –27dB @ 250MHz
The PI3DBV10 is a 2- to 1-Channel multiplexer/demultiplexer
Video 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 video source to one of two corresponding
outputs, or switch two inputs to a common display. 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 LVDS and TMDS.
• Near-Zero propagation delay: 250ps
• Switching speed: 9ns
• Channel On Capacitance: 9pF (typical)
• VCC Operating Range: +3.0V to +3.6V
• ESD>2000V . . . Human Body Model
• >500 MHz bandwidth (or data frequency)
• Packaging:
-Pb-free & Green,12-contact TDFN (ZE)
Application
• Routes physical layer signals for high bandwidth

Notes:
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 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.

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.
