Receivers provide ‘industry leading’ rf performance
1 min read
Silicon Laboratories has introduced a new family of radio receivers tuned for high end consumer and professional audio equipment.
The company says that the Si477x am/fm receivers provide industry leading rf performance and configurability as well as reduce system cost and complexity for consumer audio/video receivers, fm receiver monitors and pro audio receivers.
The family of devices includes the Si4770, a global multiband am/fm receiver, and the Si4777, an am/fm receiver which supports hd radio tuner functionality. Both include Silicon Labs' digital low IF architecture and are designed to reduce the bill of materials in audio applications. With -3.5dBµV sensitivity, the Si477x receivers are said to be able to tune to signals down to 0.67µV and pick up stations up to 100miles away.
The receivers also feature an on-chip 'prosumer' fm channel equaliser designed to eliminate multipath fading and deliver optimal performance under complex multipath interference conditions. Silicon Labs claims the the equaliser is the first of its kind in the audio industry.
"Silicon Labs' high performance Si477x receiver family provides the best value and system cost savings for high end consumer and pro-audio audio systems without compromising one decibel of radio performance," commented James Stansberry, vp and general manager of Silicon Labs' broadcast products. "Audio equipment developers evaluating radio receiver solutions will appreciate the exceptional RF performance, single chip integration, design simplicity and configurability that the Si477x family offers."
