CBTL06DP211

CBTL06DP211 DisplayPort Gen1 2 : 1 multiplexer Rev. 1 — 21 February 2011 Product data sheet 1. General description CBTL06DP211 is a multi-channel high-speed multiplexer meant for DisplayPort (DP) v1.1a or Embedded DisplayPort applications operating at data rate of 1.62 Gbit/s or 2.7 Gbit/s. It is designed using NXP proprietary high-bandwidth pass-gate technology and it can be used for 1 : 2 switching or 2 : 1 multiplexing of four high-speed differential AC-coupled DP channels. Further, it is capable of switching/multiplexing of Hot Plug Detect (HPD) signal as well as Auxiliary (AUX) and Display Data Channel (DDC) signals. In order to support GPUs/CPUs that have dedicated AUX and DDC I/Os, CBTL06DP211 provides an additional level of multiplexing of AUX and DDC signals delivering true flexibility and choice. CBTL06DP211 consumes very low current in operational mode (less than 1 mA typical) and provides for a shutdown function (ultra low current consumption less than 10 μA) to support power-sensitive or battery-powered applications. It is designed for delivering optimum performance at DP data rates of 1.62 Gbit/s and 2.7 Gbit/s. A typical application of CBTL06DP211 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 ...
