DIGITAL RAMP MODULATION MODE
In digital ramp modulation mode (Figure 24), the modulated
DDS signal control parameter is supplied directly from the
digital ramp generator (DRG). The ramp generation parameters
are controlled through the serial I/O port.
Rev. 0 | Page 18 of 60
The ramp generation parameters allow the user to control both
the rising and falling slopes of the ramp. The upper and lower
boundaries of the ramp, the step size and step rate of the rising
portion of the ramp, and the step size and step rate of the falling
portion of the ramp are all programmable.
The ramp is digitally generated with 32-bit output resolution.
The 32-bit output of the DRG can be programmed to represent
frequency, phase, or amplitude. When programmed to represent
frequency, all 32 bits are used. However, when programmed to
represent phase or amplitude, only the 16 MSBs or 14 MSBs,
respectively, are used.
The ramp direction (rising or falling) is externally controlled by
the DRCTL pin. An additional pin (DRHOLD) allows the user
to suspend the ramp generator in its present state.
