The Si2213 and Si2214 tuners offer a highly integrated tuner solution with best-in-class performance on key specifications for the XM satellite radio market.
Leveraging Silicon Laboratories’ RF CMOS expertise, the Si2213 and Si2214 significantly lower solution costs for XM radio receivers by drastically reducing the board space and component count typically required by competing solutions. The Si2213 supports the next generation single-path architectures, requiring only a single SAW filter in the entire design. The Si2214 offers a straightforward enhancement from Si2213-based designs, providing a simple approach for dual-branch systems. By integrating the functionality of two Si2213 tuners, the Si2214 is the only single-chip, dual branch solution for enhanced satellite radio service for next generation radios. Each product is offered as a solution with the Si2200. Derived from Silicon Laboratories’ industry leading Si4136XM synthesizer, the Si2200 eliminates the need for external voltage-controlled oscillators (VCOs), varactor diodes and loop filters, while eliminating RF interference issues and phase noise that are common in other designs. Both the Si2213 and the Si2214 integrate a serial-peripheral interface (SPI) allowing complete configuration and control with performance and fault monitoring through software.
