NXP Digital Single-Tuner TEF664x

High-end, DSP-based AM/FM single tuner with support for digital radio

Designed for single-tuner AM/FM & Digital Radio applications, these highly integrated RFCMOS- based solutions combine a low-IF AM/FM tuner and DSP processing on a single chip. The scalable tuner family let designers reduce component count and avoid spending time on complex system integration, without compromising performance.
