The logic input and output pins on LMKDB1112
provides different options to select device functional modes, output enable and
disable control, loss of signal (LOS) detection, and different device address
selection. The following section describes the function of different input and
output logic pins. Voltage levels for input pins can be set through TICSPro GUI or
using on-board jumper as specified in Table 3-1.
