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
