2.2 TUSB564-Q1 Equalization Control

Equalization (EQ) can be controlled using I2C or pin-strapping. Each of the TUSB564-Q1 receiver lanes has individual controls for receiver equalization (see Configuration Pin-Level Definitions). Table 3-3 and Table 3-4 list the gain values of each available combination of downstream, upstream, and DisplayPort configurations.

Table 2-2 Configuration Pin-Level Definitions
Level Settings
0 Option 1: Tie 1kΩ 5% to GND
Option 2: Tie directly to GND
R Tie 20kΩ 5% to GND
F Float (leave pin open)
1 Option 1: Tie 1kΩ 5% to VCC
Option 2: Tie directly to VCC
