7.3.3 4-Level Inputs

The TUSB544 has (I2C_EN, UEQ[1:0], DEQ[1:0], CFG[1:0], and A[1:0]) 4-level inputs pins that are used to control the equalization gain, voltage linearity range, and place TUSB544 into different modes of operation. These 4-level inputs utilize a resistor divider to help set the 4 valid levels and provide a wider range of control settings. There are internal pull-up and a pull-down resisters. These resistors together with the external resistor connection combine to achieve the desired voltage level.

Table 1. 4-Level Control Pin Settings

LEVEL SETTINGS
0 Option 1: Tie 1 KΩ 5% to GND.
Option 2: Tie directly to GND.
R Tie 20 KΩ 5% to GND.
F Float (leave pin open)
1 Option 1: Tie 1 KΩ 5%to VCC.
Option 2: Tie directly to VCC.

NOTE

All four-level inputs are latched on rising edge of internal reset. After Tcfg_hd, the internal pull-up and pull-down resistors will be isolated in order to save power.
