编码器、解码器、复用器和解复用器 GEN 1 2.7 GBPS 6CH 2:1 MULTI/DEMUX

Overview

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 ® 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 CBTL06DP211 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 CBTL06DP211 can be used in conjunction with an HDMI/DVI level shifter device PTN3360A/B or PTN3360D to allow for DisplayPort as well as HDMI/DVI connectivity.
