DAB One-Chip Channel- and Source / Data Decoder
Description
The U2739M 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 and time and frequency synchronization synchronization algorithms on OAK DSP core platform. The audio source decoder supports ISO MPEG 1, 2 layer II half and full sampling rate. The data decoder part is realized on the integrated OAK DSP core and includes 2 packet mode decoders. Several standard interfaces, like I2C/L3, I2S or RDI are implemented to offer a flexible utilization. The U2739M offers a user-defined implementation of the time and frequency synchronization by down-loading the corresponding software algorithms to the OAK DSP core. Electrostatic sensitive device. Observe precautions for handling.
