4 High Level Page

The DS320PR810 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 CTLE settings as needed for your specific application. A further description of this feature is described in Section 7.3 of the DS320PR810 data sheet.

The high level page also contains a device status page which shows which channels are detecting a signal.

1. After clicking on the high level tab, the device status page will be shown. Each channel status will be updated sequentially, and appear green if a signal is detected and red if a signal is not detected. The current EQ settings will also be shown next to each channel.
   
2. Click on the Block Diagram tab to show the following screen. Here, we can adjust the EQ values for each channel. Select a device and channel from the drop-down menu.
   
3. Select the desired EQ settings and DC gain. The EQ Index drop-down menu is the easiest way to quickly adjust the amount of equalization applied. After selecting an Index value, the Boost 1, Boost2, and Boost 1 (second order) fields will automatically populate. The user can adjust each boost value for finer tuning as needed. Refer to table 7-1 of the DS320PR810 data sheet for more information. Click the Apply to Channel or Apply to All Channels button to apply the changes.
