PS161 – DP to HDMI/DVI

DisplayPort™ to HDMI/DVI Converter

Within a DTV or monitor application, the PS161 is typically placed between the DisplayPort input and HDMI/DVI receiver circuit, which is often integrated into the DTV or monitor system chip. If an HDMI/DVI switch is used to support multiple inputs, the PS161 can be used on one of the switched inputs. The HDMI switch allows selection between multiple HDMI/DVI inputs, or the DisplayPort input via the PS161 DisplayPort to HDMI/DVI converter. The PS161 also supports DisplayPort audio, which is part of the DisplayPort standard. Along with video data, digital audio received at the PS161 DisplayPort input is retransmitted on the HDMI output.
