The Si4711 FM transmitter supports Radio Data Service (RDS) and Radio Broadcast Data Service (RBDS), enabling the display of artist and song title on an RDS/RBDS-enabled FM receiver.
"Our FM tuner and FM transmitter broadcast audio products work hand in hand to enable portable device manufacturers to cost effectively build high quality audio capabilities into their products", said Tyson Tuttle, Vice President of Silicon Laboratories.
"The FM transmitter family offers unmatched audio quality in an extremely small, highly integrated package, allowing customers to add audio features without complicating their designs".
The Si471x FM transmitter family offers customers a fully tested solution that speeds time to market and simplifies manufacturing.
It requires only two external components and is implemented in 15mm2 of printed circuit board area.
Current consumption is about one-third less than competing solutions resulting in a 33% increase in battery life.
In addition, programmable power scaling allows customers to comply with both US FCC and pending European Union transmitted power regulations with a single implementation.
The FM transmitter function easily coexists with active cellular networks as well as GPS, WLAN, Bluetooth and other wireless transmitters due to integrated on-chip filtering, reducing noise and harmonics.
Complete programmability enables one hardware solution to ship globally.
The Si4710 is sampling now to lead customers.
Pricing for the Si4710 begins at US $3.91 in quantities of 10,000.
Pricing for the Si4711, which samples in January 2007 and supports RDS/RBDS transmission, begins at $4.69 in quantities of 10,000.
A Si4710 evaluation board is available for $250.
