Digital Down Converter

Relcom's Digitral Down Converter IP Corecan be suited for decomposition of input bandpass signal into its complex envelope.

Features

14-bit input and output word length
32-bit frequency resolution DDS-based transponder
One third order CIC decimator and third order CIC interpolator for each channel
Wide range real-time variable filter characteristics
Automatic gain corrector for each channel
Input and output sample rate are equal to the clock
Direct access to the configuration parameters through individual ports
Possible Applications
Communication systems
Sofware defined radios
Channel access in all-digital receivers
Quadrature demodulators
Direct signal processing of carrier-based signals
Signal processing with an orthogonal decomposition of bandpass input signals, in the baseband
Replacement of analog DDC front-end with the advantages of stability, equal gain and linearity for I,Q channels, at a lower cost
