2.2 TUSB1064-Q1 Equalization Control

Users can control equalization (EQ) through I2C or pin-strapping. Each of the TUSB1064-Q1 receiver lanes has individual controls for receiver equalization (see Table 2-2). Reference the TUSB1064-Q1 data sheet for the gain values of each available combination of downstream, upstream, and DisplayPort configurations.
