The Broadcom BCM97110 is an advanced set-top box development
platform supporting standard definition decoding, broadband cable
modem and personal video recording (PVR). It is a highly integrated,
cost-effective design built on the latest generation of Broadcom silicon
and software offering low risk and quick time-to-market for the next
generation of interactive set-top boxes.
The triple tuner architecture allows for web browsing, video viewing,
and personal video recording (PVR) on a separate channel. Time shifting
is also simultaneously supported on the channel being viewed. The dual
MPEG-2 encoder allows full support of watch and record on 2 analog
channels.
The core chip on the BCM97110 is the BCM7110 single-chip DOCSIS
1.1/PVR IC. The BCM3125 supplies the additional QAM demodulator
and upstream burst modulator. The BCM7041 dual MPEG-2 encoder
provides the real-time encoding for analog PVR.
The BCM7110 contains a complete front-end advanced set-top box
solution providing dual 1024/256/64-QAM receivers, an out-of-band
QPSK receiver, and a QPSK to 256-QAM upstream burst modulator. All
major physical layer standards are supported allowing set-tops based on
the BCM97110 design to be deployed worldwide. The BCM7110
includes a complete DOCSIS/EuroDOCSIS 1.1 MAC (including QoS)
and DAVIC 1.2/1.5 MAC for broadband interactive services.
Features also include studio-quality text for presenting standard
Windows fonts on a standard television and a 3D graphics engine for
applications such as gaming and e-commerce.
The BCM97110 also includes a high-performance MIPS RISC processor
supporting middleware, graphics, applications, and cable modem traffic.
The single processor design eliminates the need for multiple processors
in the set-top, substantially reducing system cost.
The BCM97110 contains a number of peripherals required for nextgeneration set-top boxes. Some of these include home phoneline
networking (HPNA 1/2) for streaming of data and video throughout the
home, a VoIP module supporting 2 lines of voice, an IEEE 1394
connector for connecting to digital consumer electronic devices, hard
disk drive support for personal video recording (PVR), PCMCIA socket,
and a POD interface for external conditional access. In addition, a lowcost V.90 soft modem is included for alternative low data-rate
connections.
The BCM97110 supports industry standard operating systems,
middleware, and APIs. Driver source code for these are provided as part
of the reference design.
The BCM97110 can also expand to support high definition streams with
the HD sidecar module. This daughterboad consists of the BCM7031
HD transport, video decoder, and graphics engine. Digitial Visual
Interface (DVI) is supported with the BCM7501.
