DAB One-Chip Channel- and Source Decoder
Description
The U2739M-B is an integrated circuit in advanced CMOS technology for demodulation and decoding of a DAB signal according to ETS 300 401. The channel decoder part includes the main features OFDM demodulation & decoding and time & frequency synchronization algorithms, using the embedded OAK DSP core. The source decoder consists of an audio and a data decoder part. The audio source decoder supports ISO MPEG 1,2 layer 2 and the data decoder offers 2 independent packet mode decoders. Several standard interfaces, like I2C/L3, I2S, SPDIF or RDI are implemented to offer a flexible utilization. Moreover the U2739M-B includes a mechanism to replace respectively extend certain software modules by using a special boot mode (so-called USE). For example, the time & frequency synchronization modules can be replaced by down-loading the corresponding user software algorithms to the OAK DSP core. Electrostatic sensitive device. Observe precautions for handling.
