Diagnose AK4454VN I2S Connection
Budget: $30 – $250 USD
The AK4454VN DAC in my design feeds a Dante module over I²S, yet the system remains silent. My main objective is to uncover the exact point of failure and restore audio. Wiring continuity has already been confirmed, so the focus now shifts to schematic accuracy, pin-level compatibility, clocks, and any configuration that could be muting the DAC.
You will receive the current diagram showing MCLK, BCLK, LRCLK, SD, power rails, and the Dante interface. Please compare it against the AK4454VN datasheet and the Dante board’s requirements, then flag anything that would prevent sound output.
Deliverables
• Marked-up copy of the schematic (PDF/PNG) with corrections or questions noted.
• Brief explanation for every suggested change, tied to specific datasheet pages or timing specs.
• If the wiring proves correct, a concise checklist of register settings or external clock tests to perform next.
Acceptance criteria
– All comments reference exact AK4454VN pin numbers or signal names.
– Recommendations leave Dante module hardware untouched.
Key terms: I²S, AK4454VN, Dante, schematic review, audio signal integrity.
