Abstract
In this paper, the design of an all-digital quadrature up and down converter with high accuracy and flexible IF settings is presented. The signal up/downconversion is achieved by interpolation/decimation combined with a programmable anti-alias filter preserving the selected frequency band during the sample rate conversion. This way a high-speed solution with low-power consumption is achieved. We used a novel technique to implement flexible IF settings. The resulting structure is capable of handling signals up to 160 MSPS and is suitable for coaxial access network modem applications.
