Conexant Unveils Advanced Modulation Satellite Set-Top Box Tuner
Conexant Systems, Inc., the worldwide leader in semiconductor solutions for broadband communications, enterprise networks and the digital home, unveiled on Monday a third-generation satellite tuner for digital satellite set-top box receivers.
The CX24118 direct down-conversion satellite tuner supports 8PSK advanced modulation and coding specifications, providing satellite operators with up to 35 percent higher data throughput rates using existing bandwidth.
The highly integrated tuner can be used in conjunction with Conexant's CX24114 advanced modulation satellite demodulator, providing manufacturers with a complete front-end system solution designed to offer optimal system performance. "Our third-generation satellite tuner, when combined with our new demodulator, allows operators to leverage their existing infrastructure and provide their customers with a wider range of digital-quality programming content and services," said Jeff Crosby, vice president of Set-top Box Products for Conexant.
"Conexant has shipped more than 80 million satellite tuners and demodulators to date, and we will continue to leverage our extensive experience to provide advanced system solutions that meet the cost and performance specifications operators require to address an increasingly competitive marketplace."
The highly integrated CX24118 has been designed to meet the stringent performance parameters required for advanced modulation 8PSK and DBS-S2 applications. This tuner offers excellent phase noise performance and very low implementation loss.
Features include a fully integrated local oscillator and variable baseband filtering. The device requires a single +3.3V supply and features very low power consumption. The CX24118 has also been designed to reduce bill-of-material (BOM) costs and board space requirements.
It is packaged in a small footprint (6mm x 6mm), 36-pin pack QFN, lead-free package and does not require an external balun which reduces overall bill-of-material costs. It also includes a built-in automatic tuning machine that eliminates the need for a software calibration routine and accelerates the calibration time.
