PROFILE REGISTERS
There are eight consecutive serial I/O addresses (0x0E to 0x15)
dedicated to device profiles. All eight profile registers are either
single tone profiles or QDUC profiles depending on the device
operating mode specified by CFR1 Bits<25:24>. During
operation, the active profile register is determined via the
external PROFILE<2:0> pins.
Single tone profiles control: DDS frequency (32 bits), DDS
phase offset (16 bits), and DDS amplitude scaling (14 bits).
Rev. 0 | Page 55 of 60
QDUC profiles control: DDS frequency (32 bits), DDS phase
offset (16 bits), output amplitude scaling (8 bits), CCI filter
interpolation factor, inverse CCI bypass, and spectral invert.
The QDUC profiles also selectively apply to the interpolating
DAC operating mode: only output scaling, CCI filter
interpolation factor, and inverse CCI bypass apply; all others
(DDS frequency, output amplitude scaling, and spectral invert)
are ignored.

Spectral Invert
Description
This 6-bit number is the rate interpolation factor for the CCI filter.
0: The modulator output takes the form: I(t) × cos(
ct) – Q(t) × sin(
ct).
1: The modulator output takes the form: I(t) × cos(
ct) + Q(t) × sin(
ct).
0: The inverse CCI filter is enabled.
1: The inverse CCI filter is bypassed.
This 8-bit number controls the output amplitude.
This 16-bit number controls the DDS phase offset.
This 32-bit number controls the DDS frequency.
