- Link layer
- The link service is used to discover, configure and maintain the link with devices it connects to – it does this using DPCD via the auxiliary channel. When hot-plugging is detected via the hot-plug channel, the PC (or other source device) reads the capabilities of the display via the DPCD and then configures the link though what is known as Link Training.
- A Link Layer Design for DisplayPort Interface
- PHY layer
- The PHY layer is split up into two sub-blocks, Logical and Electrical.
- The logical portion of the layer is focused on scrambling/descrambling or encoding/decoding of data.
- The electrical portion of the PHY layer is responsible for serialisation/de-serialisation, current driving and receiving, and pre-emphasis/equalisation for the main link.
