MODES OF OPERATION
OVERVIEW
The AD9957 has three basic operating modes.
Quadrature modulation (QDUC) mode (default)
Interpolating DAC mode
Single tone mode
The active mode is selected via the operating mode bits in
Control Function Register 1 (CFR1). Single tone mode allows
the device to operate as a sinusoidal generator with the DDS
driving the DAC directly.
Interpolating DAC mode bypasses the DDS, allowing the user
to deliver baseband data to the device at a sample rate lower
than that of the DAC. An internal chain of rate interpolation
filters the user data and upsamples to the DAC sample rate.
Combined, the filters provide for programmable rate interpola-
tion while suppressing spectral images and retaining the original
baseband spectrum.
QDUC mode employs both the DDS and the rate interpolation
filters. In this case, two parallel banks of rate interpolation
filters allow baseband processing of in-phase and quadrature
(I/Q) signals with the DDS providing the carrier signal to be
modulated by the baseband signals. A detailed block diagram of
the AD9957 is shown in Figure 25.
The inverse sinc filter is available in all three modes.
