**Application Note / CS3 Power Consumption

The CORSIGHT III (CS3) has an integrated sensor interface that allows high-speed or high-resolution sensors to be transmitted to the FPGA via 16 LVDS and the image data to be sent to the CPU via the internal PCIe bus.

With the Luxima LUX 1310 sensors with 1.3MP and 1050 frames per second and the two Sony sensors IMX 250 and IMX 252, we reach data transfer rates that result in a power dissipation of 20-24 watts. The temperature of the FPGA can rise to over 100 degrees. At a FPGA temperature of 115 degrees, the system switches off automatically.

Factors for raised operating temperature:

• Reading rate of the sensor

• Environment temperature

• Type of application and the resulting processing power

• Missing or bad heat dissipation in the mechanical connection

Measures against an increased operating temperature:

• The heat can be avoided by using an active cooling system with a ventilator that supplies the cooling surfaces with an air flow. With active cooling, the CS3 can be operated permanently and at full frame rate

• If active cooling is not possible, the CS3 can be operated intermittently. With an on cycle of 2:10, 2sec frame rate to 10sec no frame rate, the CS3 with LUX 1310 sensor can be operated permanently at full frame rate without active cooling. With the SONY IMX250 and IMX252 sensors, an on cycle of 1:1, 5sec frame rate to 5sec break is enough, to work permanently at full frame rate without active cooling

• A permanent use is possible with the 50% lower scanning speed of possible frame rate

• Improved heat dissipation for the mechanical connection
