FIR Filter: The DAC Matrix Magician

Thanks to the new algorithm of FPGA-MASTER2.0, the potential of the 8pcs CS43198 can be further explored and developed.

Synchronous parallel output mode:

This reduces "discrete distortion" between DACs to improve overall performance.
FIR 2x mode, FIR 4x mode:
With FPGA-MASTER 2.0, picosecond-level precise control and adjustment of the DAC clock and data is achieved, making each DAC data stream independently adjustable. Through the "delay parallel" of 4 DACs, the DACs form a hardware analog FIR filter, which averages the differences between multiple DACs, reducing distortion and effectively improving sound details and realism.

FPGA-MASTER 2.0: The Evolved Audio System Controller

After years of algorithm development, our FPGA-Master has entered generation 2.0. As the audio system controller, it directly requests audio data from the SoC and plays a major role in signal reproduction and maintaining signal integrity. It synchronizes and generates all audio clocks utilizing two NDK femtosecond oscillators to achieve a fully synchronized single clock source. The FPGA-Master 2.0 also haspicosecond-level precise control adjusts the DAC clock, and data, and constructs the FIR filter.
