Table 10. Mappings of 8/10/12-bit YCbCr422 non-sequential IO mode
In additional to the previous input formats, there are three options can be supported by the IT66121.
DE-only option can be used for those input formats without H/VSync information. Dual-edge triggering
with half bus width option can be used to reduce the necessary bus width and dual-edge triggering
with half pixel clock option allows half input pixel clock. No all the input formats listed above can
support three options and please refer to the IT66121 programming guide for more information. Some
examples shown below are the corresponding timing relations when these options are enabled.
