Parameter Description
The boards featuring ECCO+ are equipped with cable equalizers on the Camera Linl receivers.
The equalizers compensate for the attenuation of the highest frequencies of the signal along the data lines of the Camera Link cable.
The equalizers provide four selectable equalization levels:
| ● | OFF: 0 dB - The equalizers are turned off. |
| ● | LOW: The equalizers compensate for a cable attenuation of 4 dB at 1 GHz. |
| ● | MEDIUM: The equalizers compensate for a cable attenuation of 8 dB at 1 GHz. |
| ● | HIGH: The equalizers compensate for a cable attenuation of 16 dB at 1 GHz. |
The cable attenuation is proportional to the cable length and to the cable attenuation characteristic. It can be estimated as follows:
attenuation [dB] = cable_length [m] x cable_attenuation_characteristic [dB/m]
Note: An AWG28 twisted pair, commonly found in Camera Link cable assemblies exhibits a typical cable_attenuation_characteristic of 1.4 dB/m
Parameter Usage
Relevance condition(s):
Condition: ECCO+ feature is available
Directive: Select the equalization level according to the actual cable attenuation.
Directive: For AWG28 cables of up to 1 meter, select OFF.
Directive: For AWG28 cables of 1 up to 4 meters, select LOW.
Directive: For AWG28 cables of 4 up to 8 meters, select MEDIUM.
Directive: For AWG28 cables of 8 up to 20 meters, select HIGH.
