Description
The Si4614 DAB/DAB+ radio processor provides
significant advances in size, power consumption, and
performance to enable DAB/DAB+ Radio reception in
automotive infotainment systems and car radios. It is
designed to work with the high-performance automotive
Si479x family of radio tuners.
The low power high performance Si4614 DAB/DAB+ Radio
processor provides channel demodulation and source
decoding of DAB/DAB+ signals delivering audio and data.
The Si4614 Radio processor provides DAB/DAB+
demodulation and decoding. In addition, the Si4614
provides an integrated clock oscillator or accepts a
reference clock and supports a selectable control interface
(SPI or I2C). The Si4614 processor system specifies a low
minimal bill of materials, notably eliminating an external
RAM memory module for channel decoding that is typically
required in third party DAB/DAB+ Radio processors.
