HD3SS212 5.4Gbps DisplayPort 1.2 2-to-1 Differential Switch
1 Features
3 Description
•
•
•
•
•
Compatible with DisplayPort 1.2 electrical standard
2:1 switching supporting data rates up to 5.4Gbps
Supports HPD switching
Wide -3dB differential BW of over 5.4 GHz
Excellent dynamic characteristics (at 2.7GHz)
– Crosstalk = –50dB
The HD3SS212 is a high-speed passive switch
capable of switching two full DisplayPort 4 lane ports
from one of two sources to one target location in an
application. For DisplayPort applications that
HD3SS212 also supports switching of the Auxiliary
(AUX) and Hot Plug Detect (HPD) signals. HPD path
is a buffer which requires a 125kΩ pull-down resistor
on the HPDC line.
– Isolation = –22dB
– Insertion loss = –1.4dB
A typical application would be a mother board that
includes two GPUs that need to drive one DisplayPort
sink. The GPU is selected by the Dx_SEL pin. The
HD3SS212 is offered in a 48-ball bfBGA package and
specified to operate from a single supply voltage of
3.3V over full industrial temperature range of –40°C to
105°C.
– Return loss = –11 dB
– Max bit-bit skew = 4 ps

8 Detailed Description
8.1 Overview
The HD3SS212 is a high-speed passive switch offered in an industry standard 48-pin u*BGA package available
in a common footprint shared by several other vendors. The device is specified to operate from a single supply
voltage of 3.3 V over the industrial temperature range of -40°C to 105°C.
The HD3SS212 is a generic 4-CH high-speed mux/demux type of switch that can be used for routing high-speed
signals between two different locations on a circuit board. The HD3SS212 will also support several other high-
speed data protocols with a differential amplitude of < 1800 mVpp and a common-mode voltage of < 2.0 V, as
with USB 3.0 and DisplayPort 1.2. For Display Port Applications the HD3SS212 also supports switching of both
the Auxiliary and Hot Plug Detect signals.
The device’s High Speed Port Selection Control input (Dx_SEL) pin can easily be controlled by an available
GPIO pin within a system.

(1) OE pin - For nomal operation, drive OE high. Driving the OE pin low will disable the switch to enable power savings.
(2) The ports which are not selected by the Control Lines will be in High Impedance State.
8.4 Device Functional Modes
The HD3SS212 can be operated in normal operation mode or in shut down mode. In normal operation, the input
ports of the HD3SS212 are routed to the output ports according to Table 8-1. In shut down mode the HD3SS212
is disabled to enable power savings with a typical current consumption of 5 µA. The functional mode is selected
through the OE input pin with High for normal operation and LOW for shut down.

9 Application and Implementation
Note
Information in the following applications sections is not part of the TI component specification, and TI
does not warrant its accuracy or completeness. TI’s customers are responsible for determining
suitability of components for their purposes. Customers should validate and test their design
implementation to confirm system functionality.
9.1 Application Information
9.1.1 AC Coupling Caps
Many interfaces require AC coupling between the transmitter and receiver. The 0402 capacitors are the
preferred option to provide AC coupling, and the 0603 size capacitors also work. The 0805 size capacitors and
C-packs should be avoided. When placing AC coupling capacitors symmetric placement is best. A capacitor
value of 0.1 µF is best and the value should be match for the ± signal pair. The placement should be along the
TX pairs on the system board, which are usually routed on the top layer of the board. There are several
placement options for the AC coupling capacitors. Because the switch requires a bias voltage, the capacitors
must only be placed on one side of the switch. If they are placed on both sides of the switch, a biasing voltage
should be provided. A few placement options are shown below. In Figure 9-1, the coupling capacitors are placed
between the switch and endpoint. In this situation, the switch is biased by the system/host controller.

In Figure 9-2, the coupling capacitors are placed on the host transmit pair and endpoint transmit pair. In this
situation, the switch on the top is biased by the endpoint and the lower switch is biased by the host controller.

If the common-mode voltage in the system is higher than 2 V, the coupling capacitors are placed on both sides
of the switch (shown in Figure 9-3). A biasing voltage of less than 2 V is required in this case.

Power Supply Recommendations
The HD3SS212 requires +3.3-V digital power sources. VDD 3.3 supply must have 0.1-µF bypass capacitors to
VSS (ground) in order for proper operation. The recommendation is one capacitor for each power terminal. Place
the capacitor as close as possible to the terminal on the device and keep trace length to a minimum. Smaller
value capacitors like 0.01-µF are also recommended on the digital supply terminals.

10 Layout
10.1 Layout Guidelines
•
Decoupling caps should be placed next to each power terminal on the HD3SS212. Take care to minimize the
stub length of the race connecting the capacitor to the power pin.
•
•
•
•
Avoid sharing vias between multiple decoupling caps
Place vias as close as possible to the decoupling cop solder pad
Widen VDD/GND planes to reduce effect if static and dynamic IR drop
The VBUS traces/planes must be wide enough to carry maximum of 2-A current

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
