Si4629-A10 High-Performance, Single-Chip AM/FM/HD/DAB/DAB+/RDS/RDBS Data Receiver Description Features The Si4629 single-chip digital receiver is a 100% CMOS digital radio broadcast receiver IC from Silicon Labs. It provides significant advances in size, power consumption, and performance to enable HD Radio/DAB/DAB+ services reception in automotive infotainment systems and car radios. The Si4629 data receiver offers a complete and costeffective platform to support global analog and digital AM, FM, and VHF band III radio standards by integrating multiband RF tuner, demodulator, and channel decoder on a single die. The high level of integration and complete system production test simplifies design-in, increases system quality, and improves reliability and manufacturability. The Si4629 supports worldwide analog AM and FM radio reception and incorporates a fully integrated decoder for the European Radio Data System (RDS) and the North American Radio Broadcast Data System (RDBS), including all required symbol decoding, block synchronization, error detection, and error correction functions. Leveraging Silicon Laboratories' proven and patented digital low intermediate frequency (Low-IF) receiver architecture, the Si4629 delivers superior RF performance and interference rejection. The solution offers autocalibrated digital tuning, and proven AM/FM seek functionality based on multiple signal quality and band parameters. The Si4629 offers highly flexible and advanced audio FM stereo-mono blend. In addition, the Si4629 provides an integrated clock oscillator or accepts a reference clock and supports a selectable control interface (SPI or I2C). - Worldwide FM band support (76–108 MHz) Worldwide AM band support (520–1710 kHz) LW band support (144–288 kHz) DAB/DAB+ Band III support (168–240 MHz) Advanced RDS/RDBS decoder AM/FM HD Radio™ support Integrated HD blend Supports WorldDMB Receiver Profiles I, II, III, and IV Integrated SRAM supporting time and frequency deinterleaving Advanced seek functionality Complete on-chip channel decode Full range of analog and digital signal quality metrics Fully-integrated VCO/PLL/synthesizer Fully-integrated advanced AGC and alignment SPI, I2C control interfaces 7x7 mm 48-pin QFN package Pb-free/RoHS compliant AEC-Q100 qualified Applications - OEM automotive infotainment systems - Aftermarket car radio systems - OEM automotive PND docking systems AGC AM LNA AMI PGA ADC Peak Detect Mixer Peak Detect VHFI VHF LNA RFREF ADC PGA AM/FM HD Radio/ DAB/ DAB+ Demod/ Decoder FM RDS/ RBDS c AGC PLL/ CLK Power Supply VCO FLASH Interface I2C / SPI Host Interface Digital Radio Receiver Copyright © 2015 by Silicon Laboratories SCLK SSB MISO MOSI INTB RSTB GPIOx NVMISO NVSSB NVMOSI NVSCLK VMEM VA VCORE VIO XTALI XTALO CLKOUT Si4629 3.3.2015 Si4629-A10 High-Performance, Single-Chip AM/FM/HD/DAB/DAB+/RDS/RDBS Data Receiver Selected Electrical Specifications Min Typ Max AM Input Frequency Parameter Symbol Frf Test Condition 520 — 1710 kHz FM Input Frequency Frf 76 — 108 MHz DAB Input Frequency Unit 168 — 240 MHz Analog Supply Voltage VA — 1.71 1.8 2.0 V Interface Supply Voltage VIO — 1.62 1.8 3.6 V Core Digital Supply Voltage VCORE — 1.62 1.8 2.0 V Memory Supply Voltage VMEM — 1.62 1.8 2.0 V Si4629-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.
