Si4614-A10 Low-Power, High-Performance DAB/DAB+ Baseband Processor Description Features 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. - DAB/DAB+ demodulator - Transmission Modes I, II, III, IV detection and decoding - DAB/DAB+ audio decoder - PAD/XPAD outputs available - FIC decoder - Ensemble info - Service list - Component info - Service linking info - Full support for data services - Packet mode - Packet mode with Data Groups - Enhanced packet mode - MOT, TPEG packet outputs - No external RAM required for channel decoding - Flash memory interface for application program load - Support for Si479x Zero-IF digital at 2.048 MS/s - On-chip crystal oscillator - Reference clock input - SPI, I2C control interfaces - 7x7 mm 48-pin QFN package - Pb-free/RoHS compliant - AEC-Q100 qualified Applications DIN2 DIFS2 ASRC/I2S DICLK2 DIN1 DIFS1 Si4614 DICLK1 - Aftermarket car radio systems - OEM automotive infotainment systems - OEM automotive PND docking systems ASRC/I2S LOUT ROUT Channel Decoder ASRC/LO Offset Correction DQPSK Demod OFDM Demod De-interleaver/ FEC Data Processing Digital Radio Receiver I2C/SPI Host Interface DFS DCLK DOUT SCLK/SCL SSB/A1 MISO/A0 MOSI/SDA INTB RSTB GPIO 0 - n SMODE Copyright © 2015 by Silicon Laboratories VMEM VA VCORE VIO Power NVMISO NVSSB NVMOSI FLASH Interface NVSCLK XTALO RCLK/XTALI CLK Gen I2S Demux IIN QIN IQFS IQCLK DAB/DAB+ Decoder 3.3.2015 Si4614-A10 Low-Power, High-Performance DAB/DAB+ Baseband Processor Selected Electrical Specifications Symbol Test Condition Min Typ Max Unit Analog Supply Voltage Parameter VA — 1.71 1.8 2.0 V Interface Supply Voltage VIO — 1.62 1.8 3.6 V Core Digital Supply Voltage VCORE — 1.71 1.8 2.0 V Memory Supply Voltage VMEM — 1.71 1.8 2.0 V Reference Clock Reference Clock Frequency RCLK Reference Clock Accuracy Reference Clock Duty Cycle — 36.864 — MHz –100 — 100 ppm 45 — 55 % Crystal Oscillator Crystal Oscillator Frequency — 36.864 — MHz Crystal Frequency Tolerance 37.209 MHz –100 — 100 ppm Load Capacitance 37.209 MHz — — 10 pF ESR 37.209 MHz — — 50 –40 25 85 °C Ambient Temperature TA Si4614-A10 Dimension Min Nom Max A 0.80 0.85 0.90 A1 0.00 0.02 0.05 b 0.18 0.25 0.30 D D2 7.00 BSC 5.20 e E Notes: 1. 2. 3. 4. 5.30 5.40 0.50 BSC 7.00 BSC E2 5.20 5.30 5.40 L 0.30 0.40 0.50 aaa 0.15 bbb 0.10 ddd 0.05 eee 0.08 All dimensions are shown in millimeters (mm) unless otherwise noted.
