Enhanced RDS data receivers
11 June 2008, Telecoms, Datacoms, Wireless, IoT

Silicon Laboratories has released two new high-performance radio data system (RDS) receivers.

These devices meet the growing demand to couple RDS traffic message channel (TMC) and open data applications (ODA) with static GPS navigation maps to dynamically route drivers around traffic anomalies. The Si4706 and Si4749 receive RDS data with great accuracy and reliability, offering high integration and performance for all classes of GPS navigation applications, including portable navigation devices (PNDs), GPS-enabled mobile devices and in-car telematics.

The Si4706 and Si4749 apply sophisticated decoding techniques and leverage the strength of Silicon Labs' digital low-IF architecture to offer high receiver sensitivity in low-signal environments, increased reliability of received RDS data and enhanced RDS synchronisation persistence. The Si4706 and Si4749 achieve 8 μV emf sensitivity with a 5% block error rate (BLER), allowing applications to receive data reliably at great distances from RDS transmitters.

The Si4706 utilises tuned resonance technology for embedded antennae to provide 'antenna-free' reception and provide audio out for GPS-enabled mobile devices and PNDs. As an automotive companion tuner for in-car telematics applications, the Si4749 is AEC-Q100 qualified and provides a full suite of received signal quality metrics for RDS alternate frequencies (AF) including RSSI, SNR, adjacent and alternate blockers, frequency offset, multipath interference and other proprietary information. This feature allows automotive tuners to quickly build and monitor AF lists to seamlessly switch the primary tuner to the highest quality channel as users move between broadcast tower coverage. This is a popular requirement in Europe where broadcast power is limited.

The Si4706 and Si4749 offer a flexible applications programming interface (API) that supports both minimal interrupts with only the very highest reliability in the RDS data, or alternatively, more interrupts more frequently, providing detailed visibility by individual RDS block. This allows the host processor to conserve power or perform RDS post-processing according to the customer preference. The devices also provide interrupt programmability on changes to RDS block A or block B, and the on-chip buffer will cache up to 11 full RDS groups with BLER.
