Si4624-A10 High-Performance, Single-Chip FM/DAB/DAB+/RDS/RBDS Data Receiver Description Features The Si4624 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 DAB/DAB+ data services reception in automotive infotainment systems and car radios. The Si4624 offers a complete and cost-effective platform to support global analog VHF Band II and digital 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 Si4624 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. The Si4624 additionally supports digital DAB and DAB+ data reception, incorporating digital channel demodulation and decoding functions. Leveraging Silicon Laboratories' proven and patented digital low intermediate frequency (Low-IF) receiver architecture, the Si4624 delivers superior RF performance and interference rejection. The solution offers autocalibrated digital tuning, and proven FM seek functionality based on multiple signal quality and band parameters. In addition, the Si4624 provides an integrated clock oscillator or accepts a reference clock and supports a selectable control interface (SPI or I2C). The Si4624 receiver system requires a minimal bill of materials and offers low power consumption, making the solution ideal for today’s infotainment systems. - Worldwide FM band support (76–108 MHz) Advanced RDS/RBDS decoder DAB/DAB+ Band III support (168–240 MHz) Supports WorldDMB Receiver Profiles I, II, III, and IV Integrated SRAM supporting time and frequency deinterleaving Advanced seek functionality Full range of analog and digital signal quality metrics Fully-integrated VCO/PLL/synthesizer Fully-integrated advanced AGC and alignment Flash memory interface for application program load 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 PGA ADC Peak Detect RFREF VHF LNA Mixer Peak Detect VHFI Peak Detect ADC PGA VHF Front-End Control VHFSW PLL/ CLK Power Supply VCO FLASH Interface DAB/ DAB+ Demod/ Decoder FM RDS/ RBDS 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 XTALO XTALI Si4624 3.3.2015 Si4624-A10 High-Performance, Single-Chip FM/DAB/DAB+/RDS/RBDS Data Receiver Selected Electrical Specifications Parameter Symbol FM Input Frequency Test Condition Frf DAB Input Frequency Min Typ Max Unit 76 — 108 MHz 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 Si4624-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.
