Si21602-C60
Dual DVB-C2/S2/S2X/T/C/S Digital TV Demodulator
Description
The Si21602C integrates two separate high-performance digital
demodulators for the DVB-C2/C, DVB-T, DVB-S2/S and DVB-S2X
standards into a single compact package. Leveraging Silicon Labs'
proven digital demodulation architecture, the Si21602C achieves
excellent reception performance for each media while significantly
minimizing front-end design complexity, cost, and power
dissipation. Connecting the Si21602C 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-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.
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 Si21602C offers an on-chip blind scanning algorithm for
DVB-S/S2/S2X and DVB-C standards, as well as blind lock
function. The Si21602C 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.
