BCM7110 SINGLE-CHIP SET-TOP BOX WITH DOCSIS 1.1 AND PVR
BCM7110 FEATURES
• Dual 1024/256/64-QAM variable symbol rate receivers
• supporting ITU-T J.83 Annex A/B/C
QPSK out-of-band receiver and a QPSK to 256-QAM
upstream burst modulator
• DOCSISTM 1.1 MAC supporting quality of service
(QoS)
• DAVIC 1.2/1.5 MAC
• Dolby AC-3/Musicam audio decoding
• Advanced 2D/3D graphics engine
• Dual NTSC/PAL video decoders
• NTSC/PAL video encoder
• BTSC decoder
• External bus interface (EBI) serving as local bus
• High-performance 250-MHz RISC MIPS32TM
processor with 16-KB Icache and 16-KB Dcache
• USB host and device (OHCI)
• Ethernet 10/100 MAC
• Personal video recording (PVR) with IDE controller,
3DES, and dedicated DMA engines
• On-board DES/DVB decryption
• Single unified memory architecture
• Software device drivers supporting multiple operating
systems and middlewares
• BCM7041 dual-MPEG encoder interface
• Other peripheral devices include IEEE 1394 interface,
POD interface, V.90 Softmodem support, LED and
UARTs
SUMMARY OF BENEFITS
• Integrated front-end and back-end results in the most
cost-effective single-chip set-top box solution with
personal video recording (PVR) and DOCSIS 1.1.
• PVR engine supports time shifting on a program being
viewed and recording of another program
simultaneously (watch and record).
• Dual tuner architecture allows for simultaneous
viewing of internet and video or two independent
program streams for watch and record PVR.
• DOCSIS 1.1 quality of service (QoS) enables
applications requiring minimum bandwidths, such as
VoIP and video conferencing.
• Support for DOCSIS 1.1, DAVIC 1.2/1.5, and DCII
enable deployment in virtually all major markets
worldwide.
• Single high-performance RISC processor is capable of
supporting today’s demanding set-top box operating
systems, applications, and cable modem traffic.
• External QAM demodulator support for simultaneous
DOCSIS and PVR watch and record.
