Si21692-D60
Dual DVB-T2/S2/S2X/T/C/S Digital TV Demodulator
Description
The Si21692D integrates two separate high-performance digital
demodulators for the DVB-T2/T/C, DVB-S2/S and DVB-S2X
standards into a single compact package. Leveraging Silicon Labs'
proven digital demodulation architecture, the Si21692D achieves
excellent reception performance for each media while significantly
minimizing front-end design complexity, cost, and power
dissipation. Connecting the Si21692D 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.
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 Si21692D offers an on-chip blind scanning algorithm for
DVB-S/S2/S2X and DVB-C standards, as well as blind lock
function. The Si21692D 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.
