SINGLE TONE MODE
A block diagram of the AD9957 operating in single tone mode
is shown in Figure 29; grayed items are inactive. In this mode,
both I and Q data paths are disabled from the 18-bit parallel
data port up to, and including, the modulator. The internal
DDS core produces a single frequency signal based on the
programmed tuning word. The user may select either the
cosine or sine output of the DDS. The sinusoid at the DDS
output can be scaled using a 14-bit amplitude scale factor (ASF)
and optionally routed through the inverse sinc filter.
Single tone mode offers the output shift keying (OSK) function.
It provides the ability to ramp the amplitude scale factor between
zero and an arbitrary preset value over a programmable time
interval.
