Digital Down Converter

A Digital Down Converter performs channel access functions in digital receivers. It is used for extracting a channel (frequency band) of interest in a wideband signal. 4DSP's wideband DDC core employs a quad DDC architecture to achieve ultra high performances. The core accepts up to 16-bit complex data and can process 1GSPS continuously. With a fully programmable architecture at all stages of the processing, this core combines flexibility and speed and can be used in combination with our dual-channel 1GSPS ADC module.
