Silicon Labs has introduced a portfolio of receivers/audio processors and multistandard digital radio ICs designed to deliver AM/FM and digital radio for the global car market.
The Si479xx family of AM/FM receivers and digital radio tuners delivers good car radio reception performance with on-chip audio processing at low cost, according to the company. The product line includes single-chip digital radio coprocessors and data receivers, and provides advanced digital radio audio decoding and data reception for analog and digital radio technology like HD Radio and DAB/DAB+.
Silicon Labs says its design is sensitive in weak signal environments, has good selectivity in the presence of blockers and also has strong immunity to multipath fading and distortion and can be used from entry-level car radios to multituner, multi-antenna designs.
To reduce time-to-market for developers, Silicon Labs offers four-channel and six-channel audio post-processing reference designs.
