The device compensates for pcb related frequency loss and signal reflections. This is especially helpful in designs with long pcb traces or when there is a FET switch in the signal path. Four levels of differential output voltage swing (VOD) and any combination of pre-emphasis using these VOD levels are supported. The output swing and preemphasis are configured through device control inputs. The available output swing levels are 300mVPP, 400mVPP, 600mVPP or 750mVPP. Therefore, the output pre-emphasis level can be configured to 0dB, 2.0dB, 2,5dB, 3.5dB, 5.5dB, 6dB, or 8dB. This is a good solution for embedded link applications, such as the connection from the GPU to the notebook internal panel. To adjust the output signal level adaptively during link training, the implementation needs to control the device control...
