3.7.2. Frequency Parameters

Table 9.  Frequency Parameters
Parameter Value Description
Phase Accumulator Precision 4 to 64 Select the required phase accumulator precision. The phase accumulator precision must be greater than or equal to the specified angular resolution.
Angular Resolution 4 to 24 or 32 Select the required angular resolution. The maximum value is 24 for small and large ROM algorithms; 32 for CORDIC and multiplier-based algorithms.
Magnitude Precision 10 to 32 Select the required magnitude precision.
Implement Phase Dithering On or Off Turn on to implement phase dithering.
Dither Level Min to Max When phase dithering is enabled you can use the slider control to adjust the dither level between its minimum and maximum values,
Clock Rate 1 to 999 MHz, kHz, Hz, mHz, Select the clock rate using units of MegaHertz, kiloHertz, Hertz or milliHertz.
Desired Output Frequency 1 to 999 MHz, kHz, Hz, mHz, Select the desired output frequency using units of MegaHertz, kiloHertz, Hertz or milliHertz.
Phase Increment Value Displays the phase increment value calculated from the clock rate and desired output frequency.
Real Output Frequency Displays the calculated value of the real output frequency.
