To configure the MIPI CSI-2 Receiver Decoder for PolarFire to support different data types and lane configurations, follow these steps:
1. **Data Types:** The IP core supports Raw-8, Raw-10, Raw-12, Raw-14, Raw-16, and RGB-888 data types. These data types can be selected based on the requirements of your application.
2. **Lane Configurations:** The IP core supports multi-lane configurations of 1, 2, 4, and 8 lanes. The number of lanes used will depend on the bandwidth and data transfer requirements of your system.
3. **Pixel Clock Configuration:** A PLL is required to generate the parallel clock (pixel clock) for the MIPI CSI-2 Receiver Decoder. The input clock to the PLL should be from the RX_CLK_R output pin of the IOG. The PLL needs to be configured to produce the parallel clock based on the MIPI_bit_clk and the number of lanes used.
4. **Configuration Parameters:** The IP core has various input and output ports for configuration parameters. These include signals for image sensor clock, pixel clock, reset signal, high-speed input data from lanes, low-power input data from lanes, and output signals for data, frame start, frame end, line start, line end, word count, data valid, and more.
5. **Timing Diagrams:** The manual provides timing diagrams for long packets and short packets to help you understand the timing requirements for data transmission and reception.
By following the guidelines provided in the Microsemi UG0806 MIPI CSI-2 Receiver Decoder for PolarFire Owner's Manual, you can successfully configure the MIPI CSI-2 Receiver Decoder for different data types and lane configurations to meet the requirements of your application
