1 Features
3 Description
•
•
Compatible with DisplayPort 1.4 electrical standard
2:1 and 1:2 switching supporting data rates up to
8.1 Gbps
HD3SS214 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. It
will also switch one source to one of two sinks. For
DisplayPort Applications, the HD3SS214 supports
switching of the Auxiliary (AUX), Display Data
Channel (DDC) and Hot Plug Detect (HPD) signals in
the nFBGA ZXH package.

Supports HPD, AUX and DDC switching
Wide differential BW of 8 GHz
Excellent dynamic electrical characteristics
VDD operating range 3.3 V ±10%
Extended industrial temperature range of
-40°C to 105°C
5 mm x 5 mm, 50-ball nFBGA package
Output enable (OE) pin disables switch to save
power
One 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.
Another application is when one source needs to
switch between one of two sinks, example would be a
side connector and a docking station connector. The
switching is controlled using the Dx_SEL and
AUX_SEL pins. The HD3SS214 operates from a
single supply voltage of 3.3 V over extended industrial
temperature range -40°C to 105°C.
