High-growth economies such as Brazil, Indonesia, India and China have an emerging middle class and rapidly growing automotive markets. The vehicle retail price in these markets must be relatively low, putting cost pressure on components in these vehicles. Additionally, automotive markets in developed economies such as the United States, European nations and Japan are also seeing an increased demand for cost-sensitive solutions after the global financial crisis that began in 2008.
Traditional technologies used in automotive AM/FM tuners are typically BiCMOS tuners with a 10.7 MHz IF tuner architecture. This technology/architecture delivers on radio reception performance, but the process and architecture are cost prohibitive for mixed-signal architectures where RF circuits are integrated with digital processing engines such as DSPs and microcontrollers in a monolithic circuit to deliver fully processed audio outputs.
