Conexant’s CX24108 is our second generation direct down-
conversion satellite tuner RF IC intended for high-volum e digital
video, audio and data receivers. When com bined with the HM1221
QPSK dem odulator/FEC IC, the CX24108 provides a com plete
broadband satellite front-end solution capable of operating from
1 to 45 Msps in the m ost dem anding satellite environm ents. It is
designed for 80+ transponder system s and is com patible with
international standards such as DVB and DSS. The highly integrated
CX24108 satellite tuner RF IC reduces DBS tuner BOM cost and
sim plifies RF layout.
Following the integrated LNA, the CX24108 downconverts the
satellite carrier directly to baseband and provides variable
baseband filtering for the I/Q signals. It also has a com pletely
integrated local oscillator. The VCO and synthesizer are built
in and do not require external resonators or varactor diodes.
All of this perform ance is available with just a single +5V supply.
Distinguishing Features
• Single-chip RF-to-baseband satellite receiver
• Zero-IF architecture elim inates the need for
im age-reject filtering
• Variable baseband filters for optim al
interference rejection
• Integrated LNA and LO with onboard VCO
and synthesizer
• Single +5V supply
