Digital Down Converter core
The eSi-DDC is a Digital Down Converter combining a Digital Frequency Synthesizer (DDS) with a Digital Mixer.
Overview
The eSi-DDC is a Digital Down Converter combining a Digital Frequency Synthesizer (DDS) with a Digital Mixer. The DDS is implemented in a resource efficient way achieving a 16x table compression. The core has an APB interface to set the frequency and phase and the data path uses AXI4-Stream interfaces for simple connectivity.
Key features
- Parameterizable core with these defaults
- 24-bit phase accumulator
- 4096 entry (equivalent) sine/cosine table
- 10-bit sine/cosine table amplitude quantization
- 16-bit input/output data
- APB interface for the control plane
- AXI4-Stream interface for the data plane
Benefits
- Standard interfacing
