The CBTL06GP213 is a six-channel (‘hex’) multiplexer for DisplayPort, HDMI and
PCI Express applications at Generation 2 (‘Gen2’) speeds. It provides four differential
channels capable of 1 : 2 switching or 2 : 1 multiplexing bidirectional, AC‑coupled
PCI Express, DisplayPort signals, USB3 SuperSpeed or DC coupled TMDS signals, using
high‑bandwidth pass‑gate technology. It provides support for high common‑mode/bias
voltage on the high‑speed differential channels. Additionally, it provides for
switching/multiplexing of the Hot Plug Detect signal as well as the AUX or DDC (Display
Data Channel) signals, for a total of six channels on the display side. The AUX and DDC
channels provide a four-position multiplexer such that an additional level of multiplexing
can be accomplished when AUX and DDC I/Os are on separate pins of the display source
device.
The CBTL06GP213 is designed for Gen2 speeds, supporting 5.0 Gbit/s for PCI Express, 5.4 Gbit/s
for DisplayPort or 6 Gbit/s for HDMI 2.0. It consumes 490 μA current (typical) in
operational mode and provides a shutdown function to support battery-powered
applications.
typical application of CBTL06GP213 is on applications where one of two GPU display sources must
be selected to connect to a display sink device or connector. A controller chip selects
which path to use by setting a select signal HIGH or LOW. Due to the non-directional
nature of the signal paths (which use high-bandwidth pass gate technology), the
CBTL06GP213 can also be used in the reverse topology, for example, to connect one
display source device to one of two display sink devices or connectors.
