Si4622-A10 High-Performance, Single-Chip FM HD-Radio™/RDS/RBDS Data Receiver Description Features The Si4622 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 data services reception in automotive infotainment systems and car radios. The Si4622 HD Radio data receiver offers a complete and cost-effective solution to support HD Radio data services reception by integrating a 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 Si4622 also supports worldwide 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 Si4622 delivers superior RF performance and interference rejection. The solution offers dynamic FM channel bandwidth control, auto-calibrated digital tuning, and proven FM seek functionality based on multiple signal quality and band parameters. In addition, the Si4622 provides an integrated clock oscillator or accepts a reference clock and supports a selectable control interface (SPI or I2C). The Si4622 receiver system specifies a minimal bill of materials and requires less than 100 mm2 of PCB space, excluding the antenna inputs, making the solution ideal for today's infotainment systems. - Worldwide FM band support (76–108 MHz) Advanced RDS / RBDS decoder FM HD Radio channel decoder Advanced seek functionality Complete on-chip channel decode Station Information Service (SIS) and Program Service Data (PSD) support Advanced Application Services (AAS) Payload for data applications Full range of analog and digital signal quality metrics Fully-integrated VCO/PLL synthesizer Fully-integrated advanced AGC and alignment SPI, I2C control interfaces No external RAM required for channel decoding Flash memory interface for application program load 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 HD Radio Demod/ Decoder Mixer Peak Detect VHFI Peak Detect ADC PGA VHFSW VHF Front-End Control PLL/ CLK Power Supply VCO FLASH Interface FM RDS/ RBDS I2C / SPI Host Interface Digital Radio Receiver SCLK SSB MISO MOSI INTB RSTB GPIOx NVMISO NVSSB Copyright © 2015 by Silicon Laboratories NVMOSI NVSCLK VMEM VA VCORE VIO XTALO XTALI Si4622 3.3.2015 Si4622-A10 High-Performance, Single-Chip FM HD-Radio™/RDS/RBDS Data Receiver Selected Electrical Specifications Parameter Symbol Test Condition Min Typ Max Unit Frf — 76 — 108 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 Input Frequency Si4622-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.
