Description
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.
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
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
immediately active at powerup). Nevertheless, there is a
possibility of downloading additional patch code via the I
interface (e.g., to adjust the demodulator to unexpected
conditions or reception impairments).
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.
An internal I
This provides a “quiet” I
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.
The Si2165 guarantees a low-cost system implementation due to
its minimal BOM and very small package footprint.
