NCO Frequency (Register 0x11E to Register 0x121)
Register 0x11E, Bits[7:0]—NCO Frequency Value[7:0]
Register 0x11F, Bits [7:0]—NCO Frequency Value[15:8]
Register 0x120, Bits[7:0]—NCO Frequency Value[23:16]
Register 0x121, Bits[7:0]—NCO Frequency Value[31:24]
This 32-bit value is used to program the NCO tuning frequency.
The frequency value to be programmed is given by the following
equation:

NCO Phase Offset (Register 0x122 and Register 0x123)
Register 0x122, Bits[7:0]—NCO Phase Value[7:0]
Register 0x123, Bits[7:0]—NCO Phase Value[15:8]
The 16-bit value programmed into the NCO phase value
register is loaded into the NCO block each time the NCO is
started or when an NCO SYNC signal is received. This process
allows the NCO to be started with a known nonzero phase.
Use the following equation to calculate the NCO phase offset value:
NCO
_
PHASE
= 2
16
× PHASE/360
where:
NCO_PHASE
is a decimal number equal to the 16-bit binary
number to be programmed at Register 0x122 and Register 0x123.
PHASE
is the desired NCO phase in degrees.

where:
NCO_FREQ
is a 32-bit twos complement number representing
the NCO frequency register.
f
is the desired carrier frequency in hertz (Hz).
f
CLK
is the AD6653 ADC clock rate in hertz (Hz).
