CBTL06GP212 High performance DisplayPort switch with high common-mode voltage support Rev. 1 — 2 May 2012 Product brief 1. General description The CBTL06GP212 is a six-channel (‘hex’) multiplexer for DisplayPort and PCI Express applications at Generation 2 (‘Gen2’) 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. 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 (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 CBTL06GP212 is designed for Gen2 speeds, at 5.0 Gbit/s for PCI Express or 5.4 Gbit/s for DisplayPort. It consumes 2 mA current (typical) in operational mode and provides a shutdown function to support battery-powered applications. A typical application of CBTL06GP212 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 pass gate technology), the CBTL06GP212 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. 2.
