CBTL03SB212 - DisplayPort Gen2 sideband signal multiplexer

General Description

The CBTL03SB212 is a sideband signal multiplexer for DisplayPort Gen2 applications.

It provides one differential channel capable of switching or multiplexing (bidirectional and AC-coupled) DisplayPort 1.2 Fast AUX or AUX signal, using high-bandwidth pass-gate technology.

Key Features

  • 1 : 2 multiplexing of DisplayPort signals ‹ 1 high-speed differential channel for Fast AUX or AUX ‹ 1 channel for DDC clock and data ‹ 1 channel for HPD.
  • High-bandwidth analog pass-gate technology.
  • Very low intra-pair differential skew (5 ps typical).
  • Switch/MUX position select.
  • Shutdown mode CMOS input.
  • Shutdown mode minimizes power consumption while switching all channels off.
  • Very low operation current of 0.2 mA typical.

CBTL03SB212 DisplayPort Gen2 sideband signal multiplexer Rev. 1 — 21 February 2011 Product data sheet 1. General description The CBTL03SB212 is a sideband signal multiplexer for DisplayPort Gen2 applications. It provides one differential channel capable of switching or multiplexing (bidirectional and AC-coupled) DisplayPort 1.2 Fast AUX or AUX signal, using high-bandwidth pass-gate technology. Additionally, it provides for switching/multiplexing of the Hot Plug Detect signal as well as the Display Data Channel (DDC) signals, for a total of three channels. A typical application of CBTL03SB212 is on motherboards where one of two GPU display sources needs to be selected to connect to a display sink device or connector.
