7.4.2 RAW Mode

When operating in Raw FPD-Link III input mode, the DS90UB954-Q1 receives RAW10 or RAW12 data from a DS90UB9x3x-Q1 serializer. The data is translated into a RAW10 or RAW12 CSI-2 video stream for forwarding to the CSI-2 transmit port. For each input port, the CSI-2 packet header VC-ID and Data Type are programmable.

DVP RAW8 data format is also supported in serializer RAW10 transmit mode with 8/10 data input bits (MSB or LSB) connected to the serializer DVP source. DVP format serializer inputs must have discrete synch signals. When paired with DS90UB913A-Q1 or DS90UB933-Q1 serializers, the DS90UB954-Q1 utilizes the HSYNC and VSYNC inputs to construct the MIPI CSI-2 Tx data packets. Ensure the Frame Valid to Line Valid setup time is configured appropriately for DVP input system use cases as a minimum setup timing is required as per Table 7-11.

In RAW mode the DS90UB954-Q1 deserializer each Rx Port can support up to:

12 bits of DATA + 2 SYNC bits for an input PCLK range of 37.5 MHz to 100 MHz (75 MHz for 913A-Q1) in the 12-bit, high frequency mode. Line rate = f_PCLK × (2/3) × 28; for example, f_PCLK = 100 MHz, line rate = (100 MHz) × (2/3) × 28 = 1.87 Gbps. Note: No HS/VS restrictions (raw).
10 bits of DATA + 2 SYNC bits for an input PCLK range of 50 MHz to 100 MHz in the 10-bit mode. Line rate = f_PCLK/2 × 28; for example, f_PCLK = 100 MHz, line rate = (100 MHz/2) × 28 = 1.40 Gbps. Note: HS/VS is restricted to no more than one transition per 10 PCLK cycles.
12 bits of DATA + 2 bits SYNC for an input PCLK range of 25 MHz to 50 MHz in the 12-bit low frequency mode. Note: No HS/VS restrictions (raw).

When operating with DVP serializer, the DS90UB954-Q1 deserializer also supports DVP formats such as YUV-422 which have the same pixel packing as RAW8, RAW10 or RAW12. For example; there are 3 YUV CSI-2 data types that have the same pixel packing as RAW10: YUV420 10 bit, YUV420 10 bit Chroma shifted or YUV422 10bit. These formats can be used as well as 8 bit and 12 bit YUV formats which adhere to the same structure as RAW8 and RAW12 respectively.
