10.7 Quadrature modulator and Numerically Controlled Oscillator (NCO)
The quadrature modulator allows the 12-bit I and Q-data to be mixed with the carrier
signal generated by the NCO.
The frequency of the Numerically Controlled Oscillator (NCO) is programmed over 32-bit
and allows the sign of the sine component to be inverted in order to operate positive or
negative, lower or upper single sideband up-conversion.
