Data Input Procedure
The LC75281E is controlled by inputting the stipulated serial data to the CE, CL, and DI pins. The data consists of
28 bits, of which 8 bits are the address and 20 bits are the data.
Note*: The 2
× command doubles the center frequency of all bands. When setting this bit to 1, applications must either
enter the band data for one of the bands in bits D1 to D19, or must set both bits D4 and D5 to 0, in which case all
other bits are ignored.
