In rasterized mode, the phase signal from the Phase Generator can be expressed exactly as an integer due to its rational fraction relationship to the system clock and the fact that no truncation of the phase vector occurs. The fidelity of the SINE/COSINE signals is therefore due only to the accuracy and precision of the SINE/COSINE table entries. Unlike the standard mode, there is no time base jitter. The effects of time base jitter described in Standard Mode of Operation do not affect a rasterized configuration.
Because there is no truncation of the phase vector from the phase accumulator and all possible values of phase have corresponding entries in the SINE/COSINE table, there is no need to compensate for or mitigate the phase error because there is no phase error. Dither and Taylor series correction are two techniques to reduce the effect of phase error. Because they are not required, they are not offered in rasterized mode.
The expected Spurious Free Dynamic Range of a rasterized design is 6 dB per bit of the output data field.
