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.
