Si4613-A10 Low-Power, High-Performance AM/FM HD Radio™ Baseband Processor Description Features The Si4613 HD Radio™ radio processor provides significant advances in size, power consumption, and performance to enable HD Radio reception in automotive infotainment systems and car radios as well as in high-end audio/video receivers and pro-audio systems. It is designed to work with the high-performance automotive Si476x and Si479x families of AM/FM radio tuners. The Si4613 HD Radio processor supports the iBiquity and NRSC-5 standards for FM In-Band-On-Channel (IBOC) and AM IBOC digital radio broadcasting. The processors support Station Information Service (SIS), Service Information Guide (SIG), Program Service Data (PSD), IBOC multicasting, and HD Radio digital audio. The Si4613 implements a version of iBiquity’s Cayenne HD Radio core, optimized for low power, cost, and footprint. It features an extremely efficient Viterbi decoder, thereby eliminating the need for an external SRAM memory module. The Si4613 HD Radio core utilizes iBiquity’s proprietary HDC codec to decode the HD radio signal and directs the HD radio audio output to other system ICs through an I2S digital audio interface. The Si4613 enables many additional features, such as real-time traffic, iTunes Tagging and Artist Experience by providing the Advanced Application Services (AAS) payload to the external application processor. The Si4613 HD Radio core was co-developed by Silicon Labs and iBiquity and is the most advanced power-efficient HD Radio processing core available today. - AM/FM HD Radio channel decoder (Si4613) Complete on-chip HDC audio source decoder FM HD1, HD2, HD3 multicast support Station Information Service (SIS) support Program Service Data (PSD) Advanced Application Services (AAS) Payload for data applications No external RAM required for channel decoding Flash memory interface for application program load On-chip crystal oscillator Reference clock input SPI, I2C control interfaces QFN 48-pin, 7x7x0.85 mm Pb-free/RoHS compliant AEC-Q100 qualified Applications - Aftermarket car radio systems - OEM automotive infotainment systems - OEM automotive PND docking systems Si4613 Channel Decoder SRC/Channel Filter OFDM Demod PSK/QAM Demod De-interleaver/ FEC HDCTM Decoder 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 NVMOSI NVSSB FLASH Interface NVSCLK XTALO RCLK/XTALI CLK Gen I2S Demux IIN QIN IQFS IQCLK Blend flag 3.3.2015 Si4613-A10 Low-Power, High-Performance AM/FM HD Radio™ Baseband Processor Selected Electrical Specifications Parameter Analog Supply Voltage Interface Supply Voltage Core Digital Supply Voltage Memory Supply Voltage Reference Clock Reference Clock Frequency Reference Clock Accuracy Reference Clock Duty Cycle Crystal Oscillator Crystal Oscillator Frequency Crystal Frequency Tolerance Load Capacitance ESR Ambient Temperature Symbol VA VIO VCORE VMEM Test Condition RCLK 37.209 MHz 37.209 MHz 37.209 MHz TA Min 1.71 1.62 1.71 1.71 Typ 1.8 1.8 1.8 1.8 Max 2.0 3.6 2.0 2.0 Unit V V V V — –100 45 37.209 — — — 100 55 MHz ppm % — –100 — — –40 37.209 — — — 25 — 100 10 50 85 MHz ppm pF °C Si4613-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.
