MAX4928A/MAX4928B
DisplayPort/PCIe Passive Switches

Detailed Description
The MAX4928A/MAX4928B high-speed passive switches
route PCI Express (PCIe) data and/or DisplayPort signals
between two possible destinations. The MAX4928A/
MAX4928B are ideal for routing signals between a graph-
ics memory controller hub (GMCH) and either a
DisplayPort or PCIe connector.
The MAX4928A/MAX4928B feature a single digital con-
trol input (SEL) to switch signal paths and a latch input
(LE) that holds the switches in a given state.
Digital Control Input (SEL)
The MAX4928A/MAX4928B provide a single digital con-
trol input (SEL) to select the signal path between the
IN_ and D_/TX_, X_ and HPD_/RX1_, and OUT_ and
AUX_/RX0_ channels. The truth tables for the
MAX4928A/MAX4928B are depicted in the
Functional
Diagrams/Truth Table. Drive SEL rail-to-rail to minimize
power consumption.
Latch Control Input (LE)
The MAX4928A/MAX4928B provide a single digital con-
trol input (LE) to latch the signal paths between the IN_
and D_/TX_, X_ and HPD_/RX1_, and OUT_ and
AUX_/RX0_ channels. When LE is driven high, the
switches are held in their previous state, regardless of
the input signal to SEL. Drive LE rail-to-rail to minimize
power consumption.
Analog Signal Levels
The MAX4928A/MAX4928B accept standard PCIe sig-
nals to a maximum of (VDD - 1.8V). Signals on the IN_+
channels are routed to either the D_+ or TX_+ channels,
signals on the X+ channel are routed to either HPD1 or
RX1+ channels, and signals on the OUT+ channel are
routed to either AUX+ or RX0+ channels. Signals on the
IN_- channels are routed to either the D_- or TX_- chan-
nels, signals on the X- channel are routed to either HPD2
or RX1- channels, and signals on the OUT- channel are
routed to either AUX- or RX0- channels. The
MAX4928A/MAX4928B are bidirectional switches, allow-
ing IN_, X_, OUT_, D_, TX_, HPD_, RX_, and AUX_ to be
used as either inputs or outputs.
Applications Information
DisplayPort/PCIe Switching
The MAX4928A/MAX4928B primary applications are
aimed to switch between a GMCH and either a
DisplayPort or PCIe connector. The MAX4928A/
MAX4928B contain n-channel switches to permit differ-
ential signals to be selected between a PCIe Gen II
socket or to a DisplayPort connector. Each device han-
dles up to six pairs of signals. The DisplayPort signal is
an AC-coupled 8b/10b encoded differential signal
ranging up to 2.7 Gbps. The PCIe Gen I and Gen II sig-
nals are AC-coupled, 8b/10b encoded differential sig-
nals ranging up to 5.0Gbps.
Board Layout
High-speed switches require proper layout and design
procedures for optimum performance. Keep design-
controlled impedance PCB traces as short as possible
or follow impedance layouts per the PCIe specification.
Ensure that power-supply bypass capacitors are
placed as close as possible to the device. Multiple
bypass capacitors are recommended. Connect all
grounds and the exposed pad to large ground planes.
