The DS90UB964-Q1 receives RAW8, RAW10, or RAW12 data from a DS90UB933-Q1 or
DS90UB913A-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.
Each Rx Port can support up to:
- 12 bits of DATA + 2 SYNC bits for an
input PCLK range of 37.5MHz to 100MHz (75MHz for DS90UB913A-Q1) in the 12-bit,
high-frequency mode. Line rate = PCLK × (2/3) × 28. For example, PCLK = 100MHz, line
rate = (100MHz) × (2/3) × 28 = 1.87Gbps. Note: No HS/VS restrictions (raw). The back
channel rate must be set to 2.5Mbps in this mode.
- 12 bits of DATA + 2 bits SYNC for an
input PCLK range of 25MHz to 50MHz in the 12-bit, low-frequency mode. Line rate = PCLK ×
28. For example, PCLK = 50MHz, line rate = 50MHz × 28 = 1.40Gbps. Note: No HS/VS
restrictions (raw). The back channel rate must be set to 2.5Mbps in this mode.
- 10 bits of DATA + 2 SYNC bits for an
input PCLK range of 50MHz to 100MHz in the 10-bit mode. Line rate = (PCLK / 2) × 28. For
example, PCLK = 100MHz, line rate = (100 MHz / 2) × 28 = 1.40Gbps. Note: HS/HV is
restricted to no more than one transition per 10 PCLK cycles. The back channel rate must
be set to 2.5Mbps in this mode.
The DS90UB964-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.
