adcX_ZZ_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. |
adcX_ZZ_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. |
adcX_ZZ_nco_phase_rst |
In |
s_axi_aclk |
NCO phase reset. Used to align the phases across
the converter. |

adcX_nco_update_req |
In |
s_axi_aclk |
Asserted High to request an update of the NCO
settings. |
adcX_nco_update_busy |
Out |
s_axi_aclk |
Update busy register. High when the NCO update
is in progress. |
- X refers to
the location of the tile in the converter column. ZZ is
either 01 (the lower RF-ADC
in the tile) or 23 (the upper RF-ADC in the tile)
