CARLSBAD, Calif. — MaxLinear Inc. (NYSE: MXL), a leading provider of integrated radio frequency (RF) and mixed-signal integrated circuits for broadband communications applications, announced today that Mitsumi Corp. has started mass production shipments of its latest generation of six-channel “time shift” TV network interface modules (NIM) for use in Japanese televisions based on MaxLinear’s MxL683.

The time-shift technology is an advanced DVR feature that lets consumers automatically record all of the programs on their six favorite broadcast TV channels within a rolling 15-day period. The time-shift feature allows users more time to watch their favorite TV shows without setting their TV to record a specific show. The time-shift feature is combined with regular DVR capability that allows TV viewers to designate particular shows for recording.

MaxLinear’s MxL683 integrates MaxLinear’s state-of-the-art RF tuner with a best-in-class ISDB-T demodulator in a single CMOS chip. The MxL683 provides excellent RF signal reception and digital TV signal demodulation performance due to the optimized on-chip interface and signal processing partitioning between the tuner and demodulator blocks.

The MxL683 has been shipping since the third quarter of 2012 and is based on MaxLinear’s fourth-generation of digital CMOS advanced radio and digital demodulator technology. It is fully compliant with the Japanese ISDB-T (ARIB STD-B21) and Brazilian SBTVD-T (ABNT NBR 15604) terrestrial TV receiver specifications.

“We are excited that our MxL683 has been selected by Mitsumi for its latest time-shift NIM platforms,” said Brian Sprague, MaxLinear’s Vice President and General Manager for Broadband and Consumer Products. “We are pleased that our fourth-generation CMOS RF broadband technology, the platform on which MxL683 was built, is enabling TV design innovation and market growth of TV sets with new features.”

Technical Highlights

The MxL683 sets a new benchmark for reception sensitivity with a noise figure lower than 4dB and exceptional demodulator C/N performance.

The MxL683 is fully compliant with the Japanese ISDB-T (ARIB STD-B21) and Brazilian SBTVD-T (ABNT NBR 15604) terrestrial TV receiver specifications. Additional features include auxiliary channel decoding for emergency broadcast warning systems, high accuracy receiver signal strength indicator (RSSI), and a fast channel scan algorithm to reduce channel scan time by up to 50 percent.

MxL683 provides market-leading low power consumption of 450mW for the entire tuner + demodulator receive chain and is available in a 7x7mm standard 48-pin QFN package.
