SN75DP149: Display Port DP to Digital Visual Interface converter

Part Number: SN75DP149
Other Parts Discussed in Thread: SN65DP149

Hi

I am looking for Display Port DP to Digital Visual Interface converter

Will this component work in an application as described below?

  • Display Port: DP1.2A
  • Digital Visual Interface: DVI-D (single link)
  • Active converter required due to DP1.2A
  • Screen resolution of 1024x768
  • Temperature range Industrial: -40 ° to 85 °C
  • We use 2 of 4 Lanes only.

Component datasheets I have reviewed:

SNx5DP149 3.4 Gbps DP++ to HDMI Retimer: http://www.ti.com/lit/ds/symlink/sn75dp149.pdf
SNx5DP149 3.4 Gbps DP++ to HDMI Retimer (Rev. C): http://www.ti.com/lit/ds/symlink/sn65dp149.pdf
SNx5DP159 6 Gbps DP++ to HDMI Retimer http://www.ti.com/lit/ds/symlink/sn65dp159.pdf
SNx5DP159 6 Gbps DP++ to HDMI Retimer http://www.ti.com/lit/ds/symlink/sn75dp159.pdf

Control:

  • Component named as:   … DP++ to HDMI

    Features: “Support DisplayPort Dual-Mode Standard Version 1.1”

  • Description: “…retimer supporting digital video interface (DVI) 1.0 and high-definition multimedia interface…”
    • Thus supports DP1.2A having active converter, correkt?

    • Thus supports DVI-D (single link), correkt?

  • SNx5DP149 supports screen resolution 1024x768, correkt?

  • Available with “Temperature range Industrial: -40 ° to 85 °C” according to data sheet, OK

  • According to description of DisplayPort Ver.1.2 Overview
    http://www.vesa.org/wp-content/uploads/2010/12/DisplayPort-DevCon-Presentation-DP-1.2-Dec-2010-rev-2b.pdf har vi
    • Mandantory 1 x Main Link, AUX CH, Hot Plug Detect, Powered Connector (DP_PWR pin)

    • Optional: 2xMain Link

    • Optional: 4xMain Link

Thus no problem that we uses 2 av 4 Lanes only, correct?

 

  • Hi Urban,

    SN65DP149 seems like a good fit for your application but I think it isn't.
    It seems you are looking for an active converter from DP1.2a to DVI; unfortunately, we don't have active converters, these devices are passive converters from DP++ to HDMI/DVI, please check if you GPU supports DP++.
