Si2111/13/15

The Si2115/13/11 digital TV receiver integrates a complete digital TV tuner and a DVB-T and/or DVB-C digital demodulator into a single, monolithic, CMOS mixed-signal IC.

Leveraging Silicon Labs' proven 3rd-generation digital low-IF tuner architecture, the Si2115/13/11 delivers a higher number of received channels in real-world crowded spectrum conditions without the need for external LNAs, tracking filters, or SAW filters.

An enhanced version of the proven DVB-T/C demodulator technology from Silicon Labs' Si2165 has been incorporated into the Si2115/13/11 to deliver superior performance under a wide variety of field conditions. The digital demodulator uses sophisticated on-chip algorithms to ensure optimal reception even under difficult transmission conditions. In addition, the Si2115/13/11 offers on-chip Blindscan and Blindlock scanning algorithms for DVB-C as well as DSP-assisted DVB-T fast channel scanning.

By combining digital tuner and demodulator functions in a single device, the Si2115/13/11 enables a full TV receiver solution in a very small PCB footprint and with minimal external components. The Si2115/13/11 contains an on-chip crystal oscillator and only requires the connection of a standard 24 MHz crystal or a reference clock. For dual-receiver applications, the primary Si2115/13/11 can provide a reference clock on its XOUT pin directly to the XTAL_I pin of the secondary Si2115/13/11, thus saving the cost of one crystal. The Si2115/13/11 programmable Transport Stream interface provides both serial and parallel modes, and is fully compatible with all MPEG decoders and conditional access modules (CI/CI+) to support any customer application.
