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.

Symmetry Electronics is an authorized Silicon Labs distributor.
