Si2165

Multi-Standard DVB-T and DVB-C Demodulator

Description

Features

The Si2165 is a compact standalone DVB-T/C digital TV

demodulator ideally matching Silicon Labs’ Si2170/1/2 new

hybrid high-performance silicon tuner product family. The analog

front-end consists of two ADCs with wide dynamic range (12-bit)

to allow operation with standard IF (~36 MHz), Low-IF, or Zero-IF

inputs. This enables the use of the Si2165 with any TV tuner,

either metal can or silicon tuner based.

- DVB-T (ETSI EN 300 744) demodulator & FEC decoder

- ITU J.83 Annex A/C and DVB-C (EN 300 429) compliant

demodulator & FEC decoder

- NorDig Unified 2.0, D-Book & C-Book 4.0 compliant

- Suitable for low power design: 140 mW (typical, 36 MHz IF

sampling mode)

The multi-standard demodulator supports all modes of DVB-T

(EN 300 744), including hierarchical modes. The Si2165 also

supports ITU J.83 annex A/C and DVB-C (EN 300 429),

including a user-configurable 31-tap equalizer. In addition to

DVB-T's legacy modes, the Si2165 also complies with DVB-H

(EN 300 744 Annex F) specificities: 4K FFT, extended TPS,

“native” and “in-depth” deinterleavers. The Si2165 is able to

receive DVB-H programs in fixed receiver applications (without

decoding the additional MPE FEC layer).

An embedded 32-bit DSP controls device operation.

Sophisticated on-chip algorithms ensure optimum reception

even under difficult channel conditions, such as echoes outside

the guard interval, pre-echoes, or strong impulse noise. For

ease-of-use, DSP firmware is preloaded into ROM (device is

- Dual 12-bit ADCs: accept 1 IF, low IF, or zero-IF inputs

- DVB-T channel bandwidth: 5, 6, 7, 8 MHz

- DVB-C symbol rate: 1 to 7.2 MBaud

- DSP-based synchronization and control with embedded ROM

code avoids need for code download at startup

- Supports patch code downloads for in-field upgradeability

- Independent AGC controls (for IF & RF), 

plus RSSI measurement

- ACI filtering: fixed 8 MHz SAW filter even for 7 MHz channel

- Advanced performance for SFN networks

- Impulsive noise protection algorithm

- Ultra fast automatic UHF/VHF band scanning (QuickScan)

- Master TS output modes, parallel or serial

immediately active at powerup). Nevertheless, there is

possibility of downloading additional patch code via the I C

interface (e.g., to adjust the demodulator to unexpected

conditions or reception impairments).

(with tri-state function)

Thanks to proprietary features, the Si2165 supports ultra-fast

channel scanning for VHF/UHF terrestrial and cable DTV

channels. For supported tuners, the Quickscan algorithm for

blindscan is running onto the embedded DSP (in order to limit the

host CPU load) and is provided as a downloadable patch file.

Serial or parallel master MPEG TS output modes are supported.

Furthermore, a TS slave parallel mode is available via a GPIF port

and provides a glueless interface to Silicon Labs' MCU devices

with embedded USB interface. The user can optionally program a

32-PID hardware filter to reduce the output TS bit rate.

- Slave TS parallel output: external device polls data from an

embedded FIFO, providing a seamless interface to any USB

controller.

- On-chip PID filtering to reduce TS output bit rate.

- Up to six GPIOs

- Two 5 V tolerant I C control buses (host-side, tuner-side) 

with on-chip I C repeater

- 4, 16, 20, 24, or 27 MHz clock/crystal reference

- 3.3 and 1.2 V power supplies only

- Very compact QFN-36, 5 x 6 mm, RoHS compliant package

An internal I C pass-through logic switch acts as an I C repeater.

This provides a “quiet” I C bus to the RF front end.

A maximum of six general-purpose inputs/outputs are available;

three GPIOs also feature / and interrupt output capabilities.

Best-in-class demodulation performance is achieved while still

maintaining very low-power operation.

Applications

- Digital terrestrial and cable STB, NIM, and iDTV set

- Personal Video Recorder (DVD or HDD-based)

- Digital terrestrial and cable PC-TV tuner peripheral

The Si2165 guarantees a low-cost system implementation due to

its minimal BOM and very small package footprint.
