UPO7000L-AUDIO

UPO7000L-AUDIO – Digital Audio Bus Decode Option (I²S, LJ, RJ, TDM)

🎧 Unlock Professional Audio Bus Analysis on the UPO7000L Series

The UPO7000L-AUDIO software unlock enables decoding and triggering for the most widely used digital audio serial protocols, including I²S (Inter-IC Sound), Left Justified (LJ), Right Justified (RJ), and TDM (Time Division Multiplexed audio). Ideal for engineers working in automotive infotainment, professional audio, digital signal processing, or embedded audio systems, this feature gives you deep visibility into timing, synchronization, and data payloads across multi-bit audio streams.

Whether you’re debugging codec interfaces or validating synchronization between digital microphones and DSPs, this option makes audio-level protocol validation seamless and reliable.

🔍 Supported Audio Bus Protocols

🧠 Real-World Use Cases

✅ Automotive Infotainment Systems

Decode I²S signals between the head unit and audio amplifiers or external DSPs. Identify alignment issues, channel misrouting, or dropouts caused by clock instability or harness issues.

✅ Pro Audio Equipment Debug

Use TDM decode to validate proper audio channel packing and time-slot assignments in digital mixing consoles or networked audio nodes.

✅ Embedded Voice Interfaces

Verify LJ or RJ formats when integrating digital microphones into voice-controlled devices. Ensure consistent sampling and synchronization with embedded processors.

✅ Codec & DAC/ADC Integration

Capture and analyze bit-level timing between MCLK, BCLK, WS, and SD lines. Quickly identify framing errors, signal overlap, or setup/hold violations.

🔧 Features & Capabilities

• Trigger on frame start, word select edge, or data pattern

• Visual decode overlay for serial data streams

• Event tables show timestamped audio frames

• Adjustable sample width and bit alignment parameters

• Supports mono/stereo or multichannel TDM stream formats
