Si21622-C60
Dual DVB-T2/T/C2/C Digital TV Demodulator
Description
The Si21622C integrates two separate high-performance digital
demodulators for the DVB-T2/T, and DVB-C2/C standards into a
single compact package. Leveraging Silicon Labs' proven digital
demodulation architecture, the Si21622C achieves excellent
reception performance for each media while significantly
minimizing front-end design complexity, cost, and power
dissipation. Connecting the Si21622C to a dual terrestrial/cable TV
tuner results in a high-performance and cost optimized TV
front-end solution.
Silicon Labs' internally developed DVB-C2 demodulator can
accept a standard IF (36 MHz) or low-IF input (differential) and
support all modes specified by the DVB-C2 standard. The main
features of the DVB-C2 mode are 4096-QAM, 6 or 8 MHz
bandwidth, management of notch insertion (broadband and
narrowband), and support of multiple data slices and PLPs.
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 Si21622C offers an on-chip blind scanning algorithm for the
DVB-C, as well as blind lock function. The Si21622C 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.
