Si21822-B60
Dual ISDB-T and DVB-T2/S2/S2X/T/C/S Digital TV Demodulator
Description
The Si21822 integrates two separate high-performance digital
demodulators for the Japanese and South American terrestrial
ISDB-T standard and for the DVB-T2/T, DVB-C, DVB-S2/S and
DVB-S2X standards into a single compact package. Leveraging
Silicon Labs' proven digital demodulation architecture, the
Si21822 achieves excellent reception performance for each media
while significantly minimizing front-end design complexity, cost,
and power dissipation. Connecting the Si21822 to both a dual
terrestrial/cable TV tuner, and a dual satellite tuner, results in a
high-performance and cost optimized TV front-end solution.
Leveraging significant field experience in DVB terrestrial
demodulation (DVB-T2/T), the Si21822 dual demodulator can
accept standard or low-IF inputs (differential) and complies with
the Brazilian SBTVD-T terrestrial specifications (ABNT NBR
16.601 and 15.604). Main features include fast channel scan, very
short lock times, state of the art CCI performance, partial
reception, and auxiliary channels decoding.
Silicon Labs’ internally-developed DVB-T2 (including T2-Lite)
demodulators support all modes specified by the DVB-T2 standard
(V1.4.1). Main features of the DVB-T2 mode are, SISO and MISO
support, FEF management, fully autonomous signal acquisition
including automatic L1 signaling parsing support for all pilot
patterns, and DVB-T2/T auto-detection. The DVB-T and DVB-C,
including ITU-T J.83 annex B, demodulators are enhanced
versions of proven and broadly used Si2164/67/68/69 Silicon Labs
devices.
The satellite reception allows demodulating widespread DVB-S,
DIRECTV™ (DSS), DVB-S2, DIRECTV™ (AMC) legacy
standards, and new Part II of DVB-S2 (S2X) satellite broadcast
standard. A zero-IF interface (differential) allows for a seamless
connection to market proven satellite silicon tuners. It also
integrates two DiSEqC™ 2.0 LNB interfaces for satellite dish
control and, for each satellite demodulator, an equalizer to
compensate for echoes in long cable feeds from the LNB to the
satellite tuner RF input.
The Si21822 offers an on-chip blind scanning algorithm for DVB-S/
S2/S2X and DVB-C standards, as well as blind lock function. The
Si21822 embeds two independent programmable transport stream
interfaces which provide a flexible range of output modes,
including a cross-bar functionality, and are fully compatible with all
MPEG decoders or conditional access modules to support any
customer application.
