In RAW mode, the DS90UB662-Q1 receives RAW8, RAW10, or RAW12 data from a DS90UB633A-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 DS90UB633A-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.
