In basic NCO frequency-setting mode (NCO_RDIV = 0x0000), the NCO frequency setting is set by the 32-bit register value, FREQAx and FREQBx (x = 0 to 3). The NCO frequency for DDC A can be calculated using Equation 4, where FREQAx can be replaced by FREQBx to calculate the NCO frequency for DDC B.
Changing the FREQAx and FREQBx register settings during operation results in a non-deterministic NCO phase. If deterministic phase is required, the NCOs must be resynchronized; see the NCO Phase Synchronization section.
