In RAW mode, the DS90UB960-Q1 receives RAW8, RAW10, or RAW12 data from a DS90UB933-Q1 or DS90UB913-Q1 serializer. The data is translated into a RAW8, RAW10, or RAW12 CSI-2 video stream for forwarding on one of the CSI-2 transmit ports. For each input port, the CSI-2 packet header VC-ID and Data Type are programmable.
In RAW mode, 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 DS90UB913A-Q1) in the 12-bit, high-frequency mode. Line rate = PCLK × (2/3) × 28. For example, PCLK = 100 MHz, line rate = (100 MHz) × (2/3) × 28 = 1.87 Gbps. Note: No HS/VS restrictions (raw). NOTE: The back channel rate must be set to 2.5 Mbps in this mode.
- 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. Line rate = PCLK × 28. For example, PCLK = 50 MHz, line rate = 50 MHz × 28 = 1.40 Gbps. Note: No HS/VS restrictions (raw). The back channel rate must be set to 2.5 Mbps in this mode.
- 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 = (PCLK / 2) × 28. For example, PCLK = 100 MHz, line rate = (100 MHz / 2) × 28 = 1.40 Gbps. Note: HS/HV is restricted to no more than one transition per 10 PCLK cycles. The back channel rate must be set to 2.5 Mbps in this mode.
When operating with a DVP serializer, the DS90UB960-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 10 bit. 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.
