FM tuner brings RDS radio to Walkman
phone
Sony Ericsson has adopted the Si4701 FM tuner for the W950 Walkman phone.
Sony Ericsson has adopted the Si4701 FM tuner for the W950 Walkman phone By using the highly-integrated Silicon Laboratories Si4701 with support for the Radio Data System (RDS), Sony Ericsson quickly implemented outstanding FM stereo receiver functionality in less than 20mm2 of board area on the ultraslim stylish UMTS-enabled W950 Walkman phone with mobile music capability

The Si4300 is billed as the industry's first monolithic CMOS power amplifier (PA) for GSM cellular applications.
MCU incorporates high-resolution conversion
The C8051F350 is precision mixed-signal microcontroller that integrates an eight-channel, 24bit ADC with a high-speed 8051-compatible CPU.
The Silicon Laboratories Si4701 incorporates a digital processor for the RDS and the Radio Broadcast Data System (RBDS), which includes all the required RDS/RBDS symbol decoding, block synchronisation and error detection and correction functions.
This feature enables Sony Ericsson to provide FM broadcast data such as song title, artist, and station name on the W950 Walkman phone.
The Si4701 is pin compatible with the non-RDS part, the Si4700.
"Consumers are demanding handsets with music functionality for both feature-rich phones and entry-level handsets", said Tyson Tuttle, Vice President of Silicon Laboratories.
"The performance, integration and ease of use of our FM tuner products allow manufacturers like Sony Ericsson to quickly implement world-class FM stereo as a standard feature on any handset or portable media device".
The Si4701 reduces cost while enabling superior sound quality and adjustability in critical FM receiver specifications.
Using patented technology including a field-proven, low IF digital architecture and embedded processor technology, Silicon Laboratories' FM tuners offer industry-leading performance in all FM receiver specifications and excel in real-world environments such as large cities where high immunity to blockers is critical for good reception.
The devices provide software programmability for the seek, soft mute and stereo blend parameters, all of which are fundamental to superior performance in highly variable FM broadcast environments.
