DS90UB954-Q1: Operating Near RX Port Net CSI-2 Video BW

Part Number: DS90UB954-Q1
Other Parts Discussed in Thread: DS90UB953-Q1,

Team,

According to Table 13 of the DS90UB954-Q1 datasheet, the max CSI-2 video BW per RX port is 2.528Gbps. My customer is planning to use both ports with 2x DS90UB953-Q1 to support a resolution of 3840x2160 at 60fps and 10-bit: 4.97664Gbps/2.48832Gbps video per port. Do you see any issues supporting this resolution? Just want to confirm since it is so close to the max and much higher than the 2MP/60fps per port that it is marketed for.

Thanks,

Antonio

    Hello,

    You are correct, this is a documentation error in this table 13. which will be corrected ASAP.

    The CSI-2 rate per port is up to max of 3.328Gbps for 4 lanes as outlined in section 7.4.1 and as shown in the system examples.

    Regards,
