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

The TS3DV642-Q1 is an analog differential passive mux or demux that works for many high-speed differential

interfaces with data rates up to 8.1 Gbps. The device also works for single ended signals. The TS3DV642-Q1

supports differential signaling with common mode voltage range (CMV) of 0 to 3.6 V and with differential

amplitude up to 1800 mVpp, and single ended CMOS signaling with swing limited to 0 to 5.5 V. TS3DV642-Q1

can be used as mux or demux switch for:

• HDMI 1.4 and HDMI 2.0 - up to 6 Gbps per channel

• DisplayPort (DP) for RBR, HBR, and HBR-3 data rates - up to 8.1 Gbps per lane

• Mipi DPHY interfaces such as DSI and CSI-2 - up to 4.5 Gbps per lane

• Mipi CPHY based CSI-2

• LVDS

6 Channels of the TS3DV642-Q1 are functionaly equivalent and can be used in an arbitrary fashion for

differential and single ended signals in any order. For example in Mipi DPHY applications any of the 6 differential

channels can be used for clock signals. For Mipi CPHY applications the data pins can be grouped any order to

form trio signals. For HDMI application, while TS3DV642-Q1 data signal pins are marked for specific HDMI use,

the main-link data, main-link clock, DDC, HPD, CEC can be assigned in any order if required.

9.2 Typical Application - Switching HDMI Source

The TS3DV642-Q1 can be used to switch HDMI signals. Figure 9-1 shows use case where TS3DV642-Q1

switches HDMI signals either from an external connector or from an SOC. This is a multiplexing use case. The

device can also be used as a demultiplexer where a graphics processor can be switched into one of the two

HDMI connectors. This section provides detailed design implemenation for a HDMI application where

TS3DV642-Q1 provides 2:1 multiplexing function.
