Silicon Laboratories introduced a single-chip hybrid TV receiver family designed to simplify the design of TVs, set-top boxes (STBs), Blu-ray recorders and PC accessories. The new receiver family includes the Si2185 hybrid receiver, which combines a digital/analog TV tuner, a multi-standard analog demodulator, and DVB-T and DVB-C demodulators into a fully integrated, monolithic solution. The receiver family also includes the Si2115/13/11 digital-only receivers designed for DVB-T and DVB-C digital STBs offering terrestrial and cable reception.

The new receiver family enables TV and STB developers to eliminate numerous external components such as surface acoustical wave (SAW) filters, tracking filter inductors, wirewound inductors and low-noise amplifiers (LNAs), thereby simplifying their designs.

Silicon Labs’ single-chip TV receiver architecture provides a fully optimized, integrated signal path from RF antenna input to demodulated digital or analog baseband output. In addition, the single-chip design eliminates the sensitive intermediate-frequency PCB traces used to connect a tuner to a separate demodulator, reducing the likelihood of system noise interference and degraded performance.
