CBTL06141
Gen1 display 2 : 1 multiplexer
Rev. 2 — 15 July 2010
Product data sheet
1. General description
The CBTL06141 is a six-channel (‘hex’) multiplexer for DisplayPort and PCI Express
applications at Generation 1 (‘Gen1’) speeds. It provides four differential channels
capable of 1 : 2 switching or 2 : 1 multiplexing (bidirectional and AC-coupled) PCI Express
or DisplayPort signals, using high-bandwidth pass-gate technology. Additionally, it
provides for switching/multiplexing of the Hot Plug Detect signal as well as the AUX or
DDC (Direct Display Control) 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 CBTL06141 is designed for Gen1 speeds, at 2.5 Gbit/s for PCI Express or 2.7 Gbit/s
for DisplayPort, and for inputs voltages of up to 3.3 V typical. It consumes very low current
in operational mode (less than 1 mA typical) and provides for a shutdown function (less
than 10 μA) to support battery-powered applications.
A typical application of CBTL06141 is on motherboards where one of two GPU display
sources needs to 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 passgate
technology), the CBTL06141 can also be used in the reverse topology, e.g., to connect
one display source device to one of two display sink devices or connectors.
Optionally, the hex MUX device can be used in conjunction with an HDMI/DVI level shifter
device (PTN3300A, PTN3300B or PTN3301) to allow for DisplayPort as well as HDMI/DVI
connectivity.
