PI3DBS3224
3.3V High Speed 2 : 4 Differential Mux/Demux
Features
Description
ÎÎ2:4 Differential Multiplexer/Demultiplexer
The PI3DBS3224 is a 2:4 bidirectional multiplexer for highspeed differential and single ended signal applications (up to
720 Mbps). The PI3DBS3224 can be used in a 1:4 or dual 1:2
multiplexer/demultiplexer configuration. The PI3DBS3224 offers a high BW of 1.2 GHz with channel RON of 13 Ω (Typ).
ÎÎBidirectional Operation
ÎÎCan be used in
àà Single 1:4 Configuration
àà Dual 1:2 Configuration
àà Fan out 1:2 Configuration
ÎÎHigh BW (1.2 GHz Typ)
The PI3DBS3224 can also be used to fan out a differential or
single ended signal pair to two ports simultaneously (fan-out
configuration). The BW performance is lower in this configuration.
ÎÎLow RON and CON:
àà 13 Ω RON Typ
àà 9 pF CON Typ
ÎÎESD Performance (I/O Pins)
The PI3DBS3224 operates with a 3 to 3.6V power supply. It
features ESD protection of up to ±8-kV contact discharge and
2-kV Human Body Model on its I/O pins.
àà ±8-kV Contact Discharge (IEC61000-4-2)
àà 2-kV Human Body Model per JESD22-A114E (to
GND)
ÎÎESD Performance (All Pins)
The PI3DBS3224 provides fail-safe protection by isolating the
I/O pins with high impedance when the power supply (VCC) is
not present.
àà 2-kV Human Body Model per JESD22-A114E
ÎÎSmall QFN package (3 x 3 mm, 0.4 mm pitch)
Applications
ÎÎDesktop/Notebooks Computers
ÎÎDisplayPort Auxiliary Channel Multiplexing
ÎÎUSB 2.0 Multiplexing
ÎÎNetbooks/eBooks/Tablets

Notes:
1. The propagation delay is the calculated RC time constant of the typical ON-State resistance of the switch and the specified load capacitance when driven by an
ideal voltage source (zero output impedance).
2. Output skew between center channel and any other channel.
3. Skew between opposite transitions of the same output ( |tPHL - tPLH | ).
