VD/VB5943, VD/VB1943: direction of OIF_LANE_PHY_MAP and indexing of OIF_LANE_PHY_SWAP
Hello,
the CSI-2 lane remapping of the 5 MP global shutter sensors is described differently in two documents, and I would like to know which reading is correct:
- RM0532 Rev 2 (p. 11) describes each 2-bit field of OIF_LANE_PHY_MAP (0x093A) as "lane mapping for physical lane N", i.e. field N = physical lane N, value = the logical lane it carries.
- UM3507 Rev 4, Table 99 says "0: Logic lane is mapped to physical lane 1", i.e. field = logical lane, value = physical lane.
Questions:
1. Which description is correct?
2. Does "physical lane N" correspond to balls DATAN_P / DATAN_N in the datasheet ball map?
3. Are the DATALANE1..4 bits of OIF_LANE_PHY_SWAP (0x093B) indexed by physical lane or by logical lane?
4. In 2-lane mode, what state do the two unused physical lanes take (LP-11 or high-Z)?
5. The minimum data rate per lane is given as 300 Mbps (DS14880 p. 3 and §5.2), 250 Mbps (DS14880 Appendix B, Table 43) and 600 Mbps (UM3507 §11). Which value applies to global shutter and to rolling shutter SDR?
Thank you!
