The CBTL06GP213 is a six-channel (‘hex’) multiplexer for DisplayPort, HDMI andPCI Express applications at Generation 2 (‘Gen2’) speeds. It provides four differentialchannels capable of 1?:?2 switching or 2?:?1 multiplexing bidirectional, AC?coupledPCI Express, DisplayPort signals, USB3 SuperSpeed or DC coupled TMDS signals, usinghigh?bandwidth pass?gate technology. It provides support for high common?mode/biasvoltage on the high?speed differential channels. Additionally, it provides forswitching/multiplexing of the Hot Plug Detect signal as well as the AUX or DDC (DisplayData Channel) signals, for a total of six channels on the display side. The AUX and DDCchannels provide a four-position multiplexer such that an additional level of multiplexingcan be accomplished when AUX and DDC I/Os are on separate pins of the display sourcedevice.

The CBTL06GP213 is designed for Gen2 speeds, at 5.0?Gbit/s for PCI Express or5.4?Gbit/s for DisplayPort or HDMI 1.4b 3.4?Gbit/s. It consumes 490?μA current (typical) inoperational mode and provides a shutdown function to support battery-poweredapplications.

A typical application of CBTL06GP213 is on applications where one of two GPU displaysources must be selected to connect to a display sink device or connector. A controllerchip selects which path to use by setting a select signal HIGH or LOW. Due to thenon-directional nature of the signal paths (which use high-bandwidth pass gatetechnology), the CBTL06GP213 can also be used in the reverse topology, for example, toconnect one display source device to one of two display sink devices or connectors.
