TEA685X DSP-based radio tuner one-chip Rev. 1.8 - 18 October 2013 1. General description DRAFT PDRr Ae DFRli TAm DFTRin ADFRa TADr DFRy TRAd AFDTFRa TADt Da FRTRDAs ARFDTFh ARTFADe TDFRe TRDAt ARDFTFDARTRFADTADFRTFRDATADRF The TEA685X is a single-chip AM/FM tuner family with software-defined radio signal processing. The family succeeds the industry-proven TEF662X tuner family, with improved performance and increased feature set. The devices are available in HVQFN packages occupying only smallest PCB real estate and are suitable for dual- to multi-layer PCBs. The radio receiver includes the FM/AM front-ends, tuning synthesizer, channel filtering, demodulation, FM stereo decoding, weak signal processing, noise blanking and DARC (TEA6852, TEA6853) support. Stereo audio is provided in digital format on the I2S (TEA6853) outputs and on the audio DAC outputs. The TEA6853 supports the HD Radio and Digital Radio Mondiale (DRM) digital radio standards when used with NXP Semiconductors’ digital radio coprocessors such as SAF356X and SAF360X. 2.
