DDC IP Core
A wide-band Digital Down Converter IP Core on Xilinx and Altera FPGAs that provides DSP logic required to down convert a desired frequency band. Ideal for digital receivers used in defense and aerospace applications.
The Digital Down Converter FPGA (DDC IP Core) from Mistral is a wide-band Digital Down Converter IP Core typically used in digital receivers for defense and aerospace applications. The Digital Down Converter IP Core provides the digital signal processing logic on FPGA required to down convert a desired frequency band on FPGAs. The Digital Down Converter FPGA IP Core from Mistral is designed for Programmability (Run-time), Customizability (of the IP), Optimal Resource utilization and support for Xilinx and Altera FPGAs.
The programmable DDC IP core provides digital signal processing (DSP) logic required to down-convert a desired frequency band with decimation factors of 2 to 16 in steps of 1. The principal components of the IP core are the tuner (Mixer and NCO/DDS) and the polyphase decimating filters. Features such as input/output data widths, number of filter taps, decimation factors and provision for fixed or dynamically loadable filter coefficients of the DDC IP Core are customizable as per user requirements.
