1.2.1.12 TX Channel Frequency Set
This Macro specifies the channel frequencies (or carrier frequencies) for the TX channels. It allows
configuration of up to two frequencies for each band. These are designated as NCO 1 and NCO 2 (NCO:
Numerically controlled Oscillator). The unit of the frequency value specified in the macro is determined by
the Channel Frequency Resolution macro; hence the resolution supported by this interface is either 1000
Hz or TX-DAC-RATE/2
32
. To specify a frequency in the first Nyquist zone, the frequency value should be
lower than TX-DAC-RATE/2. To specify a frequency in the second Nyquist zone, the frequency value
should fall between TX-DAC-RATE/2 and TX-DAC-RATE. Even so, the Nyquist Zone of the target TX
channel-frequency should be specified through the TX Nyquist Zone Configuration Macro.
