CBTL04DP211BS: DisplayPort 2 : 1 multiplexer
CBTL04DP211 is an (Embedded) DisplayPort multiplexer for DisplayPort v1.1a switching and multiplexing applications on PC platforms. It is capable of 1 : 2 switching or 2 : 1 multiplexing of 2-lane DisplayPort Main Link signals, using high-bandwidth pass-gate technology. Also, it can switch/multiplex Hot Plug Detect (HPD) signal and AUX signals, for a total of four channels on the display side.
To facilitate DisplayPort switching/multiplexing scheme on PC platforms suitably, CBTL04DP211 provides two separate selection pins (GPU_SEL, AUX_SEL). The selection pin GPU_SEL performs switching from one Main Link to another Main Link. HPD signals will also be switched using the same selection pin. A separate select pin (AUX_SEL) provides additional selection between two AUX channels such that the AUX channel selection is independent of the Main Link and HPD signal selection.
A typical application of CBTL04DP211 is on motherboards where one of two GPU/CPU display sources needs to be selected to connect to a DisplayPort 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 CBTL04DP211 can also be used in the reverse topology, e.g., to connect one DisplayPort source device to one of two DisplayPort sink devices or connectors.
