8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The TUSB522P is a dual-channel single-lane re-driver and signal conditioner designed to compensate for ISI

jitter caused by attenuation through passive mediums such as traces or cables. The TUSB522P has two

independent channels to allow optimization in both upstream and downstream directions through three EQ and

six De-Emphasis settings.
