Fx3 + lattice + two sensors (sc130gs) 130m (1280 * 1024), 200fps for each sensor. Is this scheme OK? Do you need to add a USB3.0 hub.

Cx3 each sensor uses 2 lanes, and each sensor can run 200fps

Hello,

Please let me know which part number are you using for your application. Is it CX3 or FX3?

CX3 can support maximum bandwidth of 2.4Gbps and FX3 can support maximum bandwidth of 3.2Gbps ( GPIF II interface). If you want frame rate of 200 than the video resolution and bits/pixel ( video format ) for both the sensors need to be adjusted such that the combined video throughput is less than the maximum supported by FX3/CX3

Rashi

>>  I understand that both the image sensors are connected to 1 FX3 via Lattice FPGA. If yes, the maximum throughput supported by GPIF II is 3.2Gbps ( 100MHz clock * 32 bits bus width). Please confirm if video throughput (h resolution * V resolution * bits/pixel*fps) from both the sensors combined is less than 3.2 Gbps.

>> I didn't understand this. Please elaborate

Rashi:

Cx3 connects two sensors (1280 * 1024 * 8bit * 200fps), and each sensor uses 2lane.

Or can you give me an optimal scheme using two sensors, which can reach 200fps? Is there any relevant design.
