USB Type-C/DP1.4a Alt-mode-to-DP++ Converter with USB Timer


The MCDP5240 is an advanced USB Type-C / DisplayPort1.4a to DP++ converter with an integrated USB type-C de-multiplexer, targeted primarily for Mobile Notebook accessory and display applications. This device functions as a DP to DP re-timer with lane count, link rate conversion option and DP to HDMI protocol converter with an HDCP1.x/ HDCP2.x repeater function.

The MCDP5240 has a DP alt-mode capable USB Type-C Upstream Facing Port (UFP). The four high speed lanes of UFP can receive DP1.4a audio-video and USB3.1 Gen2 data streams simultaneously. The input lane mapping is flexible and meets the USB Type-C connector flip orientation requirements. The incoming DP and USB signals are de-multiplexed, retimed, and transmitted on the Downstream Facing Ports (DFP). The MCDP5240 consists of a USB DFP port with USB3.1 TX and RX pair and an audio-video DFP port configured as AC coupled HDMI/DVI port, each with four high-speed lanes.
