JAJSFC7C September 2015 – July 2016 SN65DP149 , SN75DP149
PRODUCTION DATA.
SNx5DP149 can be used on the motherboard and dongle applications. The following use case diagrams show the connection of DDC between source side and sink side. The control pin pull up and pull down resistors are shown from reference. If a high is needed only use the pull up. If a low is needed only use the pull down. If mid level is to be selected do not use either resistors and leave the pin floating/No connect. The 6.5-KΩ Vsadj resistor value shown is explained further in the compliance section.
Figure 28 shows the original connection of SNx5DP149 on motherboard through the DDC channel. The DDC DR default is 100-kHz and is capable to adjust to 400-kHz.
shows the SNx5DP149 in the dongle application. It uses the unified structure on DisplayPort connector.
