ROI frame rates
200 to 300 MBps
Values were measured for typical operation in rolling shutter (RS) mode, using the
test setup defined in Exposure time and frame rate on page 30.
To reach the maximum frame rate available for typical operation, the bandwidth
for image traffic is 375 MBps. Increasing the
DeviceLinkThroughputLimit
value
may even increase frame rates if supported by the hardware used.
