Skyworks Si4694 Digital Radio Coprocessor Block Diagram
December 9, 2021 - Skyworks is pleased to introduce the
Si4694 digital radio coprocessor for DRM for AM radio reception in automotive
infotainment systems and car radios. Designed to work with Skyworks' Si479xx family
of automotive radio tuners, the Si4694 provides a new level of performance and power
efficiency with the lowest system BOM. The Si4694 is part of the Falcon family of
automotive digital radio coprocessors.
Key Features
- DRM30 coprocessor
- FAC and SDC decoder
- Multiplex info
- Packet mode
- MOT, TPEG packet outputs
- No external RAM required for channel decoding or seamless blending
- Flash memory interface for application program load
- Interfaces with Si479xx tuners and supports Zero-IF DRM30 I/Q at 192 kS/s
- Receives AM/FM audio over I2S to generate audio output
- Integrated crystal oscillator
- Reference clock input
- SPI or I2C control interface
- LGA 72-pin, 10 x 10 x 1 mm
- Pb-free/RoHS compliant
- AEC-Q100 qualified (A-grade devices)
The Si4694 provides demodulation and source decoding of DRM for AM signal delivering
audio and data. It supports all operating modes of the DRM for AM digital radio
standard (Modes A to D). The Si4694 is a highly integrated device that requires
only a few external components. The Si4694 generates its internal clocking from
an external crystal using an integrated oscillator or an external reference clock
and supports a selectable host-control interface (SPI or I2C). Combined with Skyworks'
Si479xx tuners, the Si4694 provides a complete and cost-effective DRM for AM solution.
Si4694 Specifications
- Pin/package and API compatibility with Si4692/93 digital radio coprocessors
- Interfaces with single and dual pin/package compatible tuners
- Small footprint and lowest system BOM
- Advanced radio and audio signal processing
- Offers full range of data services
