SAF3560HV/V1106K

Digital Signal Processor Dsp Overview

The SAF3560HV/V1106K is a terrestrial digital radio processor designed to demodulate and process digital baseband signals, such as HD Radio, into audio and data. It supports dual HD Radio reception for AM and FM, enabling background scanning and data services. The device integrates a microprocessor, memory controllers for SDRAM and NOR-Flash, and multiple interfaces including I2S, SPI, and I2C. Key features include conditional access support, sample rate conversion, and AEC-Q100 qualification. It operates with supply voltages of 1.2 V and 3.3 V, dissipating up to 0.5 W.

Digital Signal Processor Dsp Feature Summary

• Dual HD Radio support for AM/FM digital audio and metadata
• Conditional Access (CA) feature set included
• Supports up to 6-channel (5.1) audio via I2S interface
• Integrated SDRAM controller (up to 512 Mbit) and NOR-Flash interface

Digital Signal Processor Dsp Applications

• Automotive infotainment systems requiring HD Radio capability
• Digital terrestrial radio receivers with dual-tuner functionality
• Audio processing units supporting conditional access content

Digital Signal Processor Dsp Procurement Notes

Verify the specific subtype suffix against Table 3 in the datasheet to ensure compatibility with required HD Radio versions and tuner configurations. Confirm package availability, as the HV variant corresponds to the HLQFP144 package. Check for obsolescence status as NXP product lifecycles may vary.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring integrated digital radio decoding with conditional access. Ensure the system design accommodates the required 1.2 V and 3.3 V power domains. Verify that external SDRAM and Flash memories meet the interface specifications for the selected memory controller configuration.

Digital Signal Processor Dsp Part Context

The SAF3560 series comprises various subtypes differentiated by HD Radio version support (1.0 or 1.5), conditional access capabilities, and tuner configurations. The HV suffix indicates the HLQFP144 package option. Other variants include EL for LFBGA170 packaging and different numeric suffixes for feature sets.

Digital Signal Processor Dsp Replacement Considerations

Consult NXP Semiconductors for supported radio/audio DSP alternatives. Cross-model substitution requires verification of pin compatibility, software ecosystem support, and specific feature set requirements such as CA or dual-tuner support.
