Product Information

Back to top
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 multi-band 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.
