SAF775DHN/N208WBMP

Digital Signal Processor Dsp Overview

The SAF775DHN/N208WBMP is an audio DSP from the NXP SAF775x series, designed for mid-to-high-end automotive infotainment systems. It utilizes RFCMOS technology with a dedicated E7a DSP providing over 450MHz of audio processing capability. The device integrates two high-sensitivity on-chip tuners and supports digital radio standards including DAB. It features flexible audio routing for multiple inputs and outputs via digital interfaces like I²S and TDM, alongside analog ADC/DAC capabilities.

Digital Signal Processor Dsp Feature Summary

• Integrated dual high-sensitivity AM/FM/DAB tuners
• E7a DSP core delivering >450MHz audio processing performance
• Supports advanced audio post-processing including PEQ, GEQ, and dynamic range compression
• Rich interface suite including I²S, TDM, BBI2S, S/PDIF, and SPI

Digital Signal Processor Dsp Applications

• Mid-range automotive entertainment head units
• High-end automotive infotainment control centers
• Digital radio receiver modules (DAB/HD Radio)

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix WBMP against official NXP documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing board designs regarding the LFBGA-364 or HLQFP-176 footprint depending on the exact variant revision. Check moisture sensitivity levels and reflow soldering profiles prior to assembly.

Digital Signal Processor Dsp Selection Notes

Select this component when requiring integrated tuning and DSP functionality in a single chip for automotive applications. Compare the SAF7751, SAF7754, and SAF7755 variants within the family to determine if the specific tuner paths and HiFi2 kernel activation codes meet the target system's feature requirements.

Digital Signal Processor Dsp Part Context

This part belongs to the SAF775x CarDSP family, which combines RF tuning and digital signal processing. The N208 ROM code version indicates specific firmware capabilities. The device is engineered to reduce bill-of-materials count by integrating functions typically handled by separate tuner and DSP chips.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements are limited within the same SAF775x family (e.g., SAF775CHN/N208WBMP). Verify pinout compatibility and software configuration differences between sub-models before substitution.
