7.4.16 CSI-2 Data Identifier
The DS90UB960-Q1 MIPI CSI-2 protocol interface transmits the data identifier byte containing the values for the virtual channel ID (VC) and data type (DT) for the application specific payload data, as shown in Figure 7-10. The virtual channel ID is contained in the 2 MSBs of the data identifier byte and identify the data as directed to one of four virtual channels. The value of the data type is contained in the 6 LSBs of the data identifier byte. When partnered with a DS90UB935-Q1 or DS90UB953-Q1 serializer, the Data Type is passed through from the received CSI-2 packets. When partnered with a DS90UB933-Q1 or DS90UB913A-Q1 the received RAW mode data is converted to CSI-2 Tx packets with assigned data type and virtual channel ID.
DVP format serializer inputs must have discrete synchronization signals. When interfacing with DS90UB913A-Q1 or DS90UB933-Q1 serializers, the DS90UB960-Q1 utilizes the HSYNC and VSYNC inputs to construct the MIPI CSI-2 Tx data packets. When paired with a DVP serializer, the DS90UB960-Q1 deserializer supports RAW8, RAW10 or RAW12 as well as formats which have the same pixel packing as RAW8, RAW10 or RAW12 such as YUV-422.
For each RX Port, register defines with which channel and data type the context is associated:
- For FPD Receiver port operating in RAW input mode connected to a DS90UB933-Q1 or DS90UB913A-Q1 serializer, register 0x70 describes RAW10 Mode and 0x71 RAW12 Mode.
- RAW1x_VC[7:6] field defines the associated virtual ID transported by the CSI-2 protocol from the camera sensor.
- RAW1x_ID[5:0] field defines the associated data type. The data type is a combination of the data type transported by the CSI-2 protocol.
