The input interface is a video interface. It comprises the horizontal (HD) and vertical (VD) synchronization signal, pixel clock (PCLK), and data (DATA). Table 9-203 gives more information about these different signals. The ISIF uses the HD and VD signals provided by the sensor through the VP and IPIPEIF. The pixel clock clocks data into the ISIF at a maximum rate of 532 MHz.
Name | I/O | Function |
---|---|---|
VD | I | Vertical sync signal |
HD | I | Horizontal sync signal |
PCLK | I | Pixel clock. This signal is the pixel clock used to load image data into the ISIF. The clock controller can configure to trigger on the rising or falling edge of the PCLK signal. |
DATA | I | Data. The data interface is a 16-bit interface. When the ISIF is configured to write data to SDRAM, the write-enable signal allows an external device to control which data is to be written to SDRAM. The data input can be configured from the ISIF_MODESET.INPMOD register where it can be set to RAW, YCbCr (16 bits and 8 bits). The polarity of the data can be changed from the ISIF_MODESET.DPOL as shown in Figure 9-123. |
