2.1 DS320PR810 5-Level I/O Control Inputs

The DS320PR810 features 5-level input pins (MODE, GAIN0, GAIN1, RX_DET, EQ0_0/ADDR0, EQ1_0/ADDR1, EQ0_1, and EQ1_1) that are used to control the configuration of the device. These 5-level inputs use a resistor divider to set the valid levels to provide a wider range of control settings.
