SEOUL, Korea (AVING) -- Silicon Laboratories today announced the expansion of its successful broadcast audio portfolio to include four new FM receivers.

The new additions include full-featured devices with embedded antenna support to enable FM radio reception without an external wired headset and the industry's smallest devices for space-constrained applications. Leveraging Silicon Labs' proven RF technology, the new FM receivers make it easy to add FM functionality to an array of applications from low-cost handsets and MP3 players, where small size and low power are imperative, to stand-alone FM radios, PCs, PDAs, smart phones and USB FM receivers.

The new Si4704 and Si4705 incorporate all of the world-class features found in Silicon Laboratories CMOS Si4700 FM tuner family and are the industry's first to support an embedded antenna. The patent-pending tunable resonance circuit incorporated on-chip provides optimal signal reception and excellent sound quality with a short embedded antenna, such as a wire or PCB trace that can be integrated inside the end product casing, enabling FM radio to be added to any portable device without the need for an external headphone cable. This enables a truly wireless music experience for FM recording, clock radios and FM over speaker applications where a headset is not required. It also complements products with integrated Bluetooth technology by allowing consumers to listen to radio over wireless headsets without having to attach a headphone cable to their portable receiver.
