Fujitsu Swells Ranks Of DVB, DSS Single-Chip Contenders
San Jose--Joining the ranks of the numerous companies competing for the promising broadcast
set-top box market, Fujitsu Microelectronics is rolling out the MB86660A single chip quadrature
phase shift key modulation (QPSK) demodulator for use in digital video broadcast (DVB) and
digital satellite systems (DSS).
Over the past few months, major semiconductor vendors have been throwing their hats into the
DSS/DVB set-top box race including Philips Semiconductor, National Semiconductor, VLSI
Technology, LSI Logic, Toshiba America, Siemens Semiconductor, STMicroelectronics, NEC
and now Fujitsu.
Fujitsu's device is designed for use in consumer and commercial satellite set-top boxes, PC
receivers and satellite-ready digital VCRs. The chip has been available in Japan; however, this is
the first time Fujitsu has offered the device in North America, the company said.
The chip features a forward error correction box that is comprised of a Viterbi decoder,
deinterleaver, and a Reed-Solomon decoder and descrambler. The chip also features dual
on-chip 6-bit analog to digital converters (ADCs) that sample up to 62MHz and an on-chip
phase lock loop (PLL).
The DSS/DVB chip is available now priced at $4.95 each in 50,000 per month quantities. The
device is manufactured on a 0.35-micron CMOS standard cell process and runs at 3.3 volts.
