6.3.1 4-Level Control Inputs

The SN75LVPE3101 has (MODE, 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 four 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 6-1 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)
1Tie 1 kΩ 5% to VCC.
Note:

To conserve power, the SN75LVPE3101 disables the internal pullup and pull-down resistors of the 4-level input after the state of 4-level pins are sampled on the rising edge of the EN pin. A change of state for any four level input pin is not applied to the SN75LVPE3101 until after the EN pin transitions from low to high.
