7.3.1 4-Level Control Inputs

The TUSB1002A has (MODE, CFG1, CFG2, CH1_EQ1, CH1_EQ2, CH2_EQ1, and CH2_EQ2) 4-level inputs pins that are used to control the equalization gain and the output voltage swing dynamic range. These 4-level inputs use a resistor divider to help set the 4 valid levels and provide a wider range of control settings. These resistors together with the external resistor connection combine to achieve the desired voltage level.

Table 7-1 4-Level Control Pin Settings
LEVELSETTINGS
0Option 1: Tie 1 kΩ 5% to GND.
Option 2: Tie directly to GND.
RTie 20 kΩ 5% to GND.
FFloat (leave pin open)
1Option 1: Tie 1 kΩ 5% to VCC.
Option 2: Tie directly to VCC.
Note:

To conserve power, the TUSB1002A disables 4-level input’s internal pull-up/pull-down resistors after the state of 4-level pins have been sampled on rising edge of EN. A change of state for any four level input pin is not applied to TUSB1002A until after EN pin transitions from low to high.
