AUSTIN, Texas, June 28, 2006/Satnews Daily/ — Freescale Semiconductor said (NYSE:FSL) (NYSE:FSL.B) it has leveraged its semi-custom ASIC design capabilities and analog/mixed signal expertise to deliver an advanced satellite broadband ASIC solution to Hughes Network Systems, LLC.
Freescale said Hughes is using the ASIC in its HN family of high-performance satellite broadband terminals. The HN terminals, used in the provision of HughesNet services, deliver high-speed data, voice and video services over satellite to enterprises, government agencies, small businesses and consumers around the world.
Based on Freescale's standard-cell ASIC methodology and 90-nanometer (nm) CMOS technology, the satellite broadband ASIC solution combines wireless and analog technology from Hughes and Freescale. The ASIC device supports DVB-S and DVB-S2 standards, ACM and CCM modes. The device is designed to perform QPSK, 8PSK, H8PSK and 16APSK demodulation and decode (LDPC / BCH) functions. Key functional blocks include: DVB-S2 demodulator, DVB-S2 FEC, synchronization processor, legacy mode (DVBS) demod and FEC, stream/adapter output interface and I2C interface.
“Freescale worked with us to develop a complex ASIC critical to our product launch requirements, and not only delivered it on time for our development cycle, but also on target for the exacting specifications of our interactive satellite communications application,” said John Corrigan, senior vice president of VLSI and wireless systems at Hughes.
“The development process between Freescale's ASIC design team and Hughes has been extremely effective, considering that we collaborated on the cutting edge of DVB-S2 ASIC design for the satellite broadband industry,” said Ritu Favre, director of operations for Freescale's Application Specific Products Operation. “The successful delivery of this low-power 90-nm CMOS device to Hughes underscores the strength and responsiveness of our ASIC design team and customer engagement model.”
The DVB-S2 standard is the latest advanced satellite transmission technique from the Digital Video Broadcasting (DVB) Project, an industry-led consortium that designs global standards for digital television and data services. DVB-S2 is a major enhancement to the previous DVB-S specification used in integrated receiver/decoder (IRD) solutions to support the higher bandwidth demands of HDTV and increasing channel count requirements. It also supports improved techniques, such as adaptive coding, to maximize the use of high-value, two-way satellite transponder resources.
Freescale said the performance breakthroughs in DVB-S2 were made possible by advanced Hughes technologies including LDPC codes and advances in demodulation.
