SAF3560HV/V1102,55

Digital Signal Processor Dsp Overview

The SAF3560HV/V1102,55 is a terrestrial digital radio processor designed to demodulate and process HD Radio baseband signals into audio and data. It supports HD Radio 1.5 with dual tuner capability for background scanning and data services. The device features a powerful signal processing core, up to 6-channel I2S audio output, and an SDRAM controller supporting up to 512 Mbit. Power supplies include 1.2 V for analog/core/memory blocks and 3.3 V for DSP/general purpose/I/O interfaces. Qualified under AEC-Q100, it operates within an ambient temperature range of -40°C to +85°C.

Digital Signal Processor Dsp Feature Summary

• HD Radio 1.5 support with dual tuner capability for simultaneous reception and background scanning
• Up to 6-channel (5.1) digital audio output via I2S-bus with optional sample rate conversion
• Integrated SDRAM controller supporting up to 512 Mbit in 16-bit configuration
• AEC-Q100 qualified for automotive applications with operating temperature range of -40°C to +85°C

Digital Signal Processor Dsp Applications

• Terrestrial digital radio receivers requiring HD Radio 1.5 compliance
• Automotive infotainment systems utilizing dual-tuner functionality
• Digital audio processing units integrating metadata and conditional access services

Digital Signal Processor Dsp Procurement Notes

Verify the specific subtype suffix matches the required feature set; the 'V1102' designation indicates HD Radio 1.5 with dual tuner support and external clock compatibility from NXP DSPs. Confirm package availability aligns with design constraints, as this model is available in HLQFP144 or LFBGA170 formats. Ensure power supply rails match the specified 1.2 V and 3.3 V requirements for proper operation.

Digital Signal Processor Dsp Selection Notes

Select the SAF3560HV/V1102 variant specifically when dual tuner support and HD Radio 1.5 features are required. Single tuner variants (e.g., V1100) lack the second baseband interface necessary for concurrent station scanning. Verify that the system architecture accommodates the separate 1.2 V and 3.3 V power domains and provides sufficient SDRAM capacity for the internal memory controller.

Digital Signal Processor Dsp Part Context

The SAF3560 series serves as a dedicated digital radio processor within NXP's portfolio for terrestrial broadcast reception. It bridges the gap between analog front-ends and digital audio processing by handling complex HD Radio modulation schemes. The HV suffix typically denotes specific voltage or thermal enhancements within the product line, ensuring robust performance in demanding automotive environments.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements depend on the required HD Radio version and tuner count. For single tuner HD Radio 1.5 needs, consider the SAF3560xx/V1103. For single tuner HD Radio 1.0, the SAF3560xx/V1100 or V1101 may be suitable. Ensure any substitute maintains the same package type (HLQFP144 or LFBGA170) and pinout compatibility if board space is constrained.
