The logic input and output pins on
LMKDB1104 provides option for selecting different device modes, output enable /
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 4-1.

Note: SMBus address for the device is
Bits[7:1]. Often Rd/Wrt bit is included in the hex value depending on the different
vendors. With Rd/Wrt column shows hex value when Rd/Wrt value is
considered 0, while Without Rd/Wrt is the SMBus address.
