This session explores the implementation of an oscillator that leverages the 50MHz clock of an inexpensive FPGA to generate waveforms at ultra-high sample rates far beyond the audible range. By concentrating computational resources on the sample rate rather than bit depth, we achieve alias-free output of harmonics exceeding 100kHz. We will share practical know-how for fully integrating the entire process on-chip—from computation to audio output via a 1-bit ΔΣ DAC—without relying on microcontrollers or external DAC ICs.
