MIPI DSI Host Controller

The VS_DSI2_HOST is a DSI-2 Host Controller that provides a standard, robust, scalable, low-power, high-speed, cost-effective interface that supports a wide range of imaging solutions for mobile devices. This DSI-2 interface IP core is fully compliant with MIPI Alliance Standard for Display Serial Interface 2 (DSI-2) Version 2.2. It supports both D-PHY (up to 4 lanes) and C-PHY (up to 3 trios) interfaces with configurable PPI widths for high-speed and low-power operation. The IP provides an enhanced DPI supporting both video and command modes with programmable signal polarity and configurable pixel throughput (1 or 4 pixels per cycle), and it supports a wide range of video mode formats per DSI-2 v2.2, including various YCbCr, RGB, and compressed pixel streams up to 48-bit. In addition to BIST (color bar) mode, comprehensive error detection is implemented, covering PHY, packet, protocol, and FIFO status.
