Description

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

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

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.
