Broadcom Launches First Integrated Universal Satellite Receiver Chip to Support DVB, DSS and Primestar Satellite Systems
IRVINE, Calif.--(BUSINESS WIRE)--May 18, 1998--
Integrated Features Significantly Reduce System Design Costs
Broadcom Corp. (Nasdaq:BRCM) Monday announced the satellite broadcast industry's first integrated universal satellite
receiver chip that supports DVB, DSS(R), and Primestar(R) satellite systems.
Designated the BCM4201 Universal Satellite Receiver, Broadcom's integrated single-chip solution allows satellite receiver
manufacturers for the first time to cost effectively design a satellite Integrated Receiver Decoder (IRD) that supports all digital
transmission standards worldwide.
The BCM4201 is a highly integrated, digital transmission solution for digital satellite IRDs. It is the first satellite receiver chip to
support 480 MHz input signals, enabling users to design systems with lower cost 480 MHz output tuners. It incorporates a
2-90 Mbps variable BPSK/QPSK/OQPSK receiver, dual 8-bit A/D converters, a phase/frequency recovery block, variable
rate digital filters, square root Nyquist matched filters, acquisition and tracking loops, and a DVB/DSS/Primestar compliant
FEC decoder onto a single chip.
The BCM4201 produces an MPEG-2 or DSS compliant transport stream in either serial or parallel format. This feature-rich
device enables the same IRD design to be used for all digital satellite applications.
The BCM4201 is the first integrated digital transmission solution to have an on chip DVB/DSS/Primestar compliant FEC
decoder. This universal solution allows the device to address the entire digital broadcast satellite (DBS) market. The chip
supports the DVB digital transmission standard for satellite broadcasting, the DSS digital transmission standard used by
DIRECTV(R) licensees, and Primestar ITU-R 217/11 digital transmission standard.
With its ability to demodulate variable data rates up to 90 Mbps (45 Mbaud), the BCM4201 permits the same satellite IRD to
adapt to various satellite transponders in Europe, North America, and Asia. Because of its integrated 8-bit A/Ds, the chip can
also operate down to 1 Mbaud with excellent adjacent channel rejection characteristics, which allows the chip to be used in
single channel per carrier (SCPC) applications.
"The BCM4201 is an ideal solution for manufacturers that want to reduce their system cost by leveraging the 480 MHz input
mode and develop one receiver that supports all digital satellite applications," said Peter LaRocca, Broadcom's Product Line
manager, Satellite Products.
"When using the BCM4201, manufacturers can design one receiver to support one standard or multiple standards. This design
flexibility not only reduces the IRD manufacturer's development and manufacturing costs but also the satellite operator's costs,
which carries over to a cost savings to the subscriber."
The BCM4201 is also the first satellite receiver chip to have a direct 480 MHz IF input mode. The chip accepts an analog
baseband or IF modulated (up to 480 MHz) signal and transmits a demodulated error corrected MPEG-2/DSS transport
data stream. This front-end capability reduces the number of components needed in the tuner, which significantly decreases the
system design costs.
The BCM4201 is the second-generation satellite receiver chip from Broadcom. It incorporates several new features. The
chip's integrated dual 8-bit A/D converters and digital filters increase adjacent channel rejection, which improves the overall
performance of the receiver. These A/D converters also significantly reduce system manufacturing costs and complexities.
Additional circuitry has been added to the BCM4201 to improve tuner phase noise tracking and minimize cycle slips at very
low signal-to-noise ratios. An automatic false frequency lock detection circuit has been added to the device to minimize CPU
overhead and reduce acquisition time.
BCM4201 is packaged in an 80-pin PQFP. Samples of the BCM4201 are available today. The BCM4201 is priced at
$9.50 each in quantities of 10,000.
