Frame rates with Cropping
Values were calculated as defined in Frame rates with ROI/Cropping on page 53
and in Operation for maximum frame rates on page 55.
Frame rates at maximum bandwidth calculates for 1.051 Gbps per lane. To reach
the maximum frame rate available for typical operation, the bandwidth for image
traffic is at 2 lanes with 2.102 Gbps. Increasing the CSI-2 Lane Count value does
not increase frame rates.
