1.2.1.14 FB Channel Frequency Set
This Macro specifies the channel frequencies (or carrier frequencies) for the FB channels. It allows
configuration of up to four frequencies for each channel. These are designated as NCO 1, NCO 2, NCO 3,
and NCO 4(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 FB-ADC-RATE/2
32
. A frequency value up to FB-ADC-RATE can be specified
through this macro, so the value specified here should be the target channel-frequency modulo FB-ADC-
RATE. Note that the Nyquist zone of the target channel-frequency should be specified through the RX-FB
Nyquist Zone Configuration Macro.
