SAF775DHN/N208W/KK

Digital Signal Processor Dsp Overview

The SAF775DHN/N208W/KK is an audio DSP from the NXP SAF775x series, designed for high-performance AM/FM/DAB dual-tuner applications. It integrates advanced audio post-processing features and an open HiFi2 kernel. The device supports WB-AM/FM/HD processing in the first tuner path and FM/HD or DAB in the second path. It offers comprehensive audio interfaces including ADC/DAC, I²S, TDM, BBI2S, I²C, SPI, and S/PDIF. The component is housed in an LFBGA-364 package with moisture sensitivity classification.

Digital Signal Processor Dsp Feature Summary

• Integrated AM/FM PACS, CEQ, enhanced multipath suppression, and phase diversity
• Advanced audio post-processing with PEQ, GEQ, delay lines, compressors, expanders, tremolo, and bass enhancement
• Dual-tuner architecture supporting WB-AM/FM/HD (Path 1) and FM/HD or DAB (Path 2)
• Rich interface support including ADC/DAC, I²S, TDM, BBI2S, I²C, SPI, and S/PDIF

Digital Signal Processor Dsp Applications

• High-end car audio systems requiring AM/FM/DAB reception
• Home theater receivers with integrated radio tuners
• Portable multimedia devices with advanced audio processing needs

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix /KK against official NXP documentation to confirm pinout, ROM code version, and packaging details. Ensure compatibility with existing board designs regarding the LFBGA-364 package and moisture sensitivity handling requirements during assembly.

Digital Signal Processor Dsp Selection Notes

Select this model when dual-tuner capability with DAB support is required alongside advanced HiFi2 audio processing. Compare with SAF7754HN/N208WMP if only single-tuner functionality is sufficient, as it may offer different interface configurations or cost structures.

Digital Signal Processor Dsp Part Context

This part belongs to the SAF775x family of audio DSPs from NXP Semiconductors. Variants like SAF7751, SAF7754, and SAF7755 differ primarily in tuner paths and audio processing capabilities. The N208 ROM code version indicates specific firmware integration for AM/FM/DAB standards.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the SAF775x series include SAF775CHN/N208W/BK or SAF775DHV/N208W/CK, depending on package type (HLQFP-176 vs LFBGA-364) and specific tuner path requirements. Verify electrical and mechanical compatibility before substitution.
