AD9957 Phase Truncation


From the AD9957 datasheet it is not possible to discern the size of the sin/cos lookup table.

While the phase offset has 14 bits, they are MSB aligned with the phase akkumulator, which apparently has 32 bits, but it is nowhere mentioned how many bits are transferred to the lookup table.

Can someone please enlighten me and tell me the significant number of phase bits that are actually converted to the 14 bit (DAC resolution) sin/cos amplitude value?
