SBAS649B June 2021 – June 2022 DAC12DL3200
PRODUCTION DATA
The DAC12DL3200 contains two numerically controlled oscillators (NCOs) that can optionally be used for direct digital synthesis of tones for each DAC. The block diagram for the DDS is shown in Figure 7-22. There are two NCO banks, each with 16 separate 32-bit NCOs. The banks can be used separately for each DAC, or together to provide 32 NCOs for one DAC. The two NCOs can be summed as a two tone source for one DAC. The NCO can be selected either through registers NCO_SEL_A and NCO_SEL_B, or through balls NCOSEL[0:3] and NCOBANKSEL.
