SAF775CHN/N208WBMP

Digital Signal Processor Dsp Overview

The SAF775CHN/N208WBMP is an audio DSP from NXP Semiconductors, part of the SAF775x series. It utilizes RFCMOS technology and features a dedicated E7a DSP providing over 450MHz for audio processing. The device integrates two high-sensitivity on-chip tuners and supports digital radio standards including HD, DAB, and DRM. It offers flexible audio routing with multiple inputs and outputs, supporting both digital and analog signals via interfaces such as I²S, TDM, BBI2S, I²C, SPI, and S/PDIF. The component is housed in an HLQFP-176 package.

Digital Signal Processor Dsp Feature Summary

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix WBMP against official NXP documentation to confirm the exact reel packaging quantity and moisture sensitivity level. Ensure compatibility with the required ROM code version N208 for intended feature activation. Check current supply status as distribution may be restricted in certain regions.

Digital Signal Processor Dsp Selection Notes

Select this model when dual tuner capability and integrated digital radio support are required within a single audio DSP solution. Compare against SAF7751 or SAF775 variants if only single tuner functionality or different package constraints apply. Confirm that the HLQFP-176 package fits the target PCB layout and thermal requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the SAF775x family of CarDSP devices designed for automotive applications. These processors combine RF tuning capabilities with high-performance audio processing, allowing for simplified system architectures by integrating functions typically handled by separate chips.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the SAF775x family include SAF7751HV/N208QK and SAF7755HV/N208ZT, though pinouts and specific tuner configurations may vary. Verify functional equivalence regarding the N208 ROM code before replacement.
