SI4699-A10-GM

Overview

The SI4699-A10-GM is an automotive-grade, high-performance dual digital radio receiver integrated circuit manufactured by Skyworks Solutions. It features a 72-LGA (10x10 mm) surface-mount package and supports AM/FM, HD Radio, DAB/DAB+, and DRM30 standards. The device integrates two independent coprocessors for simultaneous processing of different broadcast formats. It operates with a supply voltage range of 1.71 V to 2 V and functions within a temperature range of -40°C to +125°C. Communication interfaces include I2C, SPI, and I2S.

Feature Summary

• Dual coprocessor architecture enabling simultaneous reception of distinct digital radio standards
• Integrated support for DAB/DAB+, AM/FM, HD Radio, and DRM30 protocols
• Automotive-grade reliability designed for harsh environmental conditions
• Compact 72-lead LGA package optimized for space-constrained vehicle installations

Applications

• Automotive infotainment systems requiring multi-standard radio reception
• Vehicle navigation units integrating digital broadcast data services
• Advanced driver assistance system (ADAS) audio integration modules
• Connected car telematics units supporting regional digital radio variants

Procurement Notes

Verify the specific suffix 'GM' confirms the lead-free and RoHS-compliant status as documented in official Skyworks datasheets. Confirm the 72-LGA package dimensions match your PCB footprint requirements precisely. Ensure your design supports the required 1.71 V to 2 V power domain and thermal dissipation for the -40°C to +125°C operating range. Validate interface compatibility for I2C, SPI, and I2S connections before finalizing the schematic.

Selection Notes

Select this component when dual-channel digital radio processing is required within a single IC solution. It is suitable for applications needing concurrent DAB/DAB+ and HD Radio functionality without external coprocessors. Consider the 72-LGA package size constraints and the need for precise voltage regulation between 1.71 V and 2 V. This part is appropriate for automotive environments demanding wide temperature tolerance and high reliability standards.

Part Context

The SI4699 belongs to Skyworks' family of digital radio receivers designed for the automotive sector. It complements other models like the SI4689 and SI4690 by offering enhanced dual-processing capabilities. While similar to the SI4699-A10-AMR, the GM suffix denotes specific packaging and compliance attributes. It serves as a core component for modern vehicle audio systems transitioning to digital broadcast standards.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing firmware if replacing legacy single-channel receivers. Check pin-to-pin compatibility with previous Skyworks generations if migrating designs.
