8.5.1 Example Register Writes

This section provides three different example register writes. Table 8-28 describes a global power-down register write, Table 8-29 describes the register writes when the scrambler is enabled, and Table 8-30 describes the register writes for 8x decimation for channels A and B (complex output, 1 DDC mode) with the NCO set to 1.8 GHz (fS = 3 GSPS) and the JESD format configured to LMFS = 4421.
