SAF775DHV/N208Q/AK

Digital Signal Processor Dsp Overview

The SAF775DHV/N208Q/AK is an audio DSP from the NXP SAF775x series, designed for high-performance AM/FM/DAB dual-tuner applications in automotive entertainment systems. It utilizes RFCMOS technology with a dedicated E7a DSP providing over 700MHz of RF processing and over 450MHz of audio processing capabilities. The device integrates two high-sensitivity on-chip tuners, core audio processing functions, and flexible audio routing supporting multiple digital and analog inputs/outputs. It features advanced audio post-processing including PEQ, GEQ, delay lines, compressors, expanders, and bass/treble enhancement.

Digital Signal Processor Dsp Feature Summary

• Advanced audio post-processing: PEQ, GEQ, delay lines, dynamics control, and bass/treble enhancement
• Flexible audio routing supporting multi-input/multi-output configurations with I²S, TDM, BBI2S, S/PDIF interfaces

Digital Signal Processor Dsp Applications

• Mid-to-high-end automotive infotainment head units
• AM/FM/DAB dual-tuner receiver modules
• Digital radio (HD/DAB/DRM) processing systems

Digital Signal Processor Dsp Procurement Notes

Verify the exact suffix 'AK' against official NXP documentation, as standard listings often use 'N208WCMP' or 'N208QK'. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements for surface mount assembly. Check for obsolescence notices or lifecycle status updates directly from NXP Semiconductors before procurement planning.

Digital Signal Processor Dsp Selection Notes

Select this component when dual-tuner capability with integrated DAB/HD Radio support is required alongside advanced audio processing. Ensure the design accommodates the LFBGA-364 package and supports the necessary digital audio interfaces (I²S/TDM). Compare with SAF7751 or SAF7754 if single-tuner or reduced feature sets are sufficient for the application.

Digital Signal Processor Dsp Part Context

This part belongs to the SAF775x family of automotive audio DSPs. Variants like SAF7751, SAF7754, and SAF7755 differ primarily in tuner paths and supported digital radio standards (e.g., DAB availability). The N208 ROM code version indicates specific firmware functionality for audio processing and tuner control algorithms.
