DVB-S FTA Satellite Set-top Box
Reference Design
Featuring the CX24138 DVB Decoder and CX24109 Satellite Tuner IC
Conexant’s portfolio includes a comprehensive suite of semiconductor
solutions for broadband communications, enterprise networks, and the
digital home. The DVB-Satellite (DVB-S) set-top box reference design
features Conexant’s CX24109 RF tuner and CX24138 satellite system-on-
chip (SoC) to provide a low-cost, high-featured, complete system solution.
The system receives and down-converts quadrature phase-shift keying
(QPSK) satellite digital video signals to baseband with the CX24109 RF
tuner. The CX24138 includes an integrated ARM920T ® main system
processor running at 100 MHz, integrated QPSK demodulator, MPEG-2
audio and video decode, and TV encoder functions. The integrated
10-bit video DACs, integrated voltage-controlled crystal oscillator (VCXO),
power-on reset circuitry, direct drive of video output connectors and clock
generation from a single crystal, coupled with a two-layer PCB and low-cost
front panel design, effectively reduce the system bill of material (BOM) cost
for STB manufacturers.
Conexant offers a complete reference design package integrating the
CX24138 with the CX24109 tuner and an unprecedented level of localized
design and sales support to accelerate development time-to-market. The
DVB-S free-to-air (FTA) satellite STB reference design kit includes samples,
schematics, layout, BOM, STB drivers, scan algorithm, user interface with
Chinese and English language support, and complete documentation of the
hardware and software system solution.
The company’s broad portfolio of semiconductor products also includes
client-side digital subscriber line (DSL) and cable modem solutions, home
network processors, broadcast video encoders and decoders, digital set-top
box components and systems solutions, and dial-up modems. In addition to
its IEEE 802.11a/b/g-compliant wireless local area network (WLAN) chipsets,
software and reference designs, Conexant offers a suite of networking
components that includes solutions for applications based on HomePlug®
and HomePNA™. Additional products include a complete line of asymmetric
and symmetric DSL central office solutions, which are used by service
providers worldwide to deliver broadband data, voice, and video over copper
telephone lines
