I have just purchased the ASI290MC and are awaiting delivery. I purchased it for the 1080p 170fps @ 10 bit which is where the "problem" arises with bandwidth over the USB 3.0 Spec.
I haven't got the item delivered yet so i haven't been able to test its capabilities and hoping someone can address this and clarify for me how it works..
The ASI290MC camera specifications state it can perform full resolution 2.1MP at 170fps in 10 Bit.
The specifications also say it uses the USB 3.0 Spec at 5Gbps
Math:
Assuming all hardware and software, on camera and in computer are all operating at their peak performance and using the theoretical maximums...
1936x1096 x 3RGB x 170fps x 10bit = 10.078Gbps.
USB 3.0 Spec is 4.8Gbps max rate - real world around 3.5Gbps.
How do they fit 10 Gbps of data from the camera into the USB 3.0 spec??
Is there compression on the camera? H.264??
Is the spec actually USB 3.1 Gen 2 (10 Gbps) ? This would then work.
In the software you can lower the USB bandwidth, but that would mean something has to give, either Resolution, framerate, bitrate, dropping to MONO or use some kind on on-camera compression.
What have i missed? Surely one of the specs are wrong??
