Si2115/13/11

Digital TV Receiver for DVB-T/C

Description

Features

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.

- Digital TV tuner

- 42–870 MHz frequency range

- No alignment, tuning or calibration

- Digital TV (DTV) demodulator and FEC decoder

- DVB-T (ETSI EN 300 744)(Si2115 and Si2111 only)

- DVB-C (ETSI EN 300 429)(Si2115 and Si2113 only)

- ITU J.83 Annex A/C (Si2115 and Si2113 only)

- Supports all DVB-T modes

- Supports DVB-C symbol rates from 1 to 7.2 MBaud

- Advanced echo equalizer

- Best-in-class real-world reception

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.

- Compliance with NorDig 2.1, D-Book, and C-Book 

specifications

- Highly integrated, lowest BOM

- No SAW filters required

- Integrated LNAs and complete tracking filters

- Customizable channel select filters

- Flexible output interface to AV processor

- Serial or parallel TS output

- Low IF output to optional external demodulator

- Single die in standard CMOS process

- 3.3 and 1.8 V power supplies

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.

- 7x7 mm, 48-pin QFN package, RoHS compliant

Applications

- Digital terrestrial or cable STB

- Digital PVR and DVD recorder

- Digital TV

- Digital PC TV card and USB dongle

- Digital full-NIM tuner module
