CBTL04DP211 - DisplayPort 2:1 multiplexer

General Description

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.

Key Features

  • Supports DisplayPort v1.1a: 1.62 Gbit/s, 2.7 Gbit/s.
  • Supports Embedded DisplayPort v1.2: 1.62 Gbit/s, 2.7 Gbit/s.
  • Supports 1-lane, 2-lane Main Link operation.
  • 1 : 2 switching or 2 : 1 multiplexing of DisplayPort Main Link signals.
  • 2 high-speed differential channels with 2 : 1 multiplexing/switching for DisplayPort Main Link signals.
  • 1 channel with 2 : 1 multiplexing/switching for AUX signals.
  • 1 channel with 2 : 1 multiplexing/switching for single-ended HPD sig.

CBTL04DP211 DisplayPort 2 : 1 multiplexer Rev. 2 — 13 April 2012 Product data sheet 1. General description 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.
