CSI2 Interface Solution

Brite provides full solution for the MIPI CSI interface, which receives the data from sensors in PHY layer, and then converts the byte data to pixel after lane data mergence. Data scramble is an optional feature to decrease the EMI effect. A standard PPI interface is implemented for the connection between MIPI PHY and CSI controller. Brite MIPI CSI interface solution supports image applications with varying pixel formats.
