6.3.2 Configuration Jumper Levels

The TDP142-Q1 EVM has 4-level inputs pins (I2C_EN, A0, and DPEQ[1:0]) that are used to control the equalization gain and place the TDP142-Q1 into different modes of operation. These 4-level inputs use a resistor divider to help set the four valid levels and provide a wider range of control settings. There are internal pullup and pulldown resistors that can combine with the external resistor connection to achieve the desired voltage level

Table 6-1 4-Level Configuration Jumper Settings
LEVELSETTINGS

Low

Tie 1kΩ 5% to GND.
RTie 20kΩ 5% to GND.
FFloat (leave pin open)

High

Tie 1kΩ 5% to VCC.

Note:

All 4-level inputs are latched on rising edge of internal reset. After tcfg_hd, the internal pullup and pulldown resistors are isolated to save power.
