B C M 7 1 0 0 F E A T U R E S
A fully featured analog and digital video cable set-
top box feature set in a single chip reduces overall
system cost dramatically.
Subsystems are based on Broadcom's field-proven
production-available technology.
Can be used in cable systems worldwide with DVB,
DAVIC, and ITU standards compatibility.
Broadcom developed device drivers enable rapid
software development cycle with support of
industry-standard operating systems.
Advanced graphics system allows applications such
as internet browsers and electronic program guides
to deliver studio-quality text and graphics on
television monitors.
Includes dual analog and digital (MPEG-2) video
system.
Supports DVS POD requirements.

The
BCM7100
is a cable set-top box system on a single chip,
integrating Broadcom's field-proven BCM3120 cable transceiver
technology, BCM7010 MPEG/AC-3 decoder technology,
BCM7014 advanced 2D/3D graphics and system integration
technology, BCM3310 MIPS microprocessor technology, all key
interfaces to external memory and I/O, and the necessary
peripherals for set-top box applications.
The
BCM7100
integrates Broadcom's field-proven and
industry- adopted QAMLink technology. This includes an in-
band 256-QAM demodulator with universal FEC supporting a
picture IF input and a 10-bit ADC, a QPSK out-of-band
demodulator with universal FEC and 6-bit ADC, and a burst
QPSK/QAM modulator with universal FEC encoding and 10-bit
DAC.
Also included in the
BCM7100
is a DAVIC 1.2/1.5 MAC able
to communicate at downstream and upstream rates of up to 3
Mbps. This DAVIC MAC includes AAL5 and SAR functionality.
The
BCM7100
back-end technology is derived from the
BCM7010 MPEG/Dolby Decoder and the BCM7014 Advanced
2D/3D Graphics Controller.
The
BCM7100
features an MPEG-2 DVB-compliant transport
demultiplexer with advanced section filtering capability, DVB
descrambler, DES descrambler, MPEG-2/DC2 video decoder,
Dolby AC3/MUSICAM audio decoder with analog and SPDIF
outputs, NTSC/PAL video encoder with MacrovisionTM and
analog output, NTSC analog video decoder with comb filtering
and time-base correction. The DES descrambler is compliant
with the DVS 213 requirements for the transport stream POD
interface. In addition, the
BCM7100
includes Broadcom's
advanced 2D/3D graphics engine, offering true studio-quality
text and graphics with extremely efficient use of memory and
bandwidth.
The
BCM7100
also incorporates a complete MIPS32-based
microprocessor subsystem, including caches with bridging to
memory and a local bus, where external peripherals can be
attached. Peripherals included in the
BCM7100
are UARTs,
two ISO7816 smart card interfaces, counter/timers, GPIO, a
POD interface, keypad, LED, IR Tx/Rx, IRDA, I2C and SPI
controllers.
