3 High Level Page

The TUSB1044 redriver features a continuous-time linear equalizer (CTLE) that applies high-frequency boost and low-frequency attenuation to help equalize the frequency-dependent insertion loss effects of a passive channel.

This page is used to quickly and easily adjust the EQ settings as needed for your specific application. A further description of this feature is described in the data sheet.

The High Level page also contains a device status page which shows which channels are detecting a signal.

   There are four modes to select:

   • USB + DisplayPort Alternate mode for Source
   • USB + DisplayPort Alternate mode for Sink

2. Select either the normal orientation or flip orientation.
   

3. Select the EQ_OVERRIDE checkbox and click the Refresh From Device button. You can then change the EQ setting for your desired channel.
