Listen to the audio recording:
This Synaptics and Mixel co-presentation covers Synaptics VXR7200 DisplayPort to Dual MIPI VR Bridge IC, integrating a Mixel C-PHY℠/D-PHY℠ Combo IP and controller. This is the world’s first announced product to support display applications using both MIPI C-PHY and D-PHY. The MIPI PHY supports aggregate data rate of up to 10 Gbps in the D-PHY mode, and 17.1Gbps in the C-PHY mode. The Synaptics R63455 VR Display Driver IC is a companion chip that drives displays using special VR display timing modes. The Synaptics IC is optimized for VR, AR, and MR dual displays headsets with resolutions up to 3Kx3K @ 120Hz with DSC compression. The MIPI interface can operate either in single-link mode, or dual-link mode.
The presentation covers the diagrams of the Synaptics IC and the Mixel IP and also shows silicon characterization results.
