1. 概述:
DDC is a complex-valued digital down-converter with a configurable number of decimation stages. The design is ideal for high sample-rate applications and permits a digital input signal to be mixed-
down and re-sampled at a lower data rate. The DDC is suitable for the down-conversion of any digitally modulated signal to baseband – an essential step before digital processing.
The DDC features a high-precision 16-bit DDS oscillator for the digital mixing stage. This oscillator is fully programmable and offers excellent phase and frequency resolution. The digital mixing stage is a complex multiplier that allows the mixing of both real and imaginary (I/Q) inputs. If only real inputs are required, then the imaginary input (q_in) should be tied low.
The output decimation stage features a configurable decimate-by-2N poly-phase filter for both I and Q channels. Each filter stage is highly optimized to use only 12 multipliers while still achieving 80 dB of stop-band attenuation.
