dacXY_nco_freq[47:0] |
In |
s_axi_aclk |
Requested NCO frequency setting. This is a 48 bit
signed input representing the NCO frequency. The value ranges from
-Fs/2 to Fs/2, where Fs is the sampling
rate. |
dacXY_nco_phase[17:0] |
In |
s_axi_aclk |
Requested NCO Phase setting. This is a 18 bit
signed number representing the NCO phase. The value ranges from -180
to 180 degrees. |
dacXY_nco_phase_rst |
In |
s_axi_aclk |
NCO phase reset. Used to align the NCO phases
across the converter. |
dacXY_nco_update_en[5:0] |
In |
s_axi_aclk |

- Bit 3: Enable write to NCO phase bits
15:0
- Bit 2: Enable write to NCO frequency bits
47:32

dacX_nco_update_req |
In |
s_axi_aclk |
Asserted High to request an update of the NCO settings. |
dacX_nco_update_busy[1:0] |
Out |
s_axi_aclk |
Update busy register
- Bit 1: High while SYSREF is disabled. Applicable for RF-DAC tile 0 when multi-tile
synchronization has been selected
- Bit 0: High when the NCO update is in
progress.
|
dac0_sysref_int_gating |
In |
s_axi_aclk |
Applicable for RF-DAC tile 0 when
multi-tile synchronization is enabled. When asserted the disabling
of the SYSREF is carried out by the IP core. |
dac0_sysref_int_reenable |
In |
s_axi_aclk |
Applicable for RF-DAC tile 0 when
multi-tile synchronization is enabled. When asserted the IP core
re-enables the SYSREF after the NCO update process has completed. In
multi-device systems all devices should be re-enabled at the same
time. |
- X refers to the
location of the tile in the converter column. Y refers to
the location of the DUC block in the tile (0 to 3).
