BCM7110 ETC, BCM7110 Datasheet - Page 2

• Manufacturer Part Number: BCM7110
• Description: SINGLE CHIP SET TOP BOX WITH DOCSIS 1.1 AND PVR
• Manufacturer: ETC

The BCM7110 is a single-chip set-top box device that combines
the key aspects required for the next generation of set-top boxes
including cost-effective single-chip design, personal video
recording (PVR), broadband communication via DOCSIS
cable modem, and support of all major global standards for
worldwide deployment.
The BCM7110 includes 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
for deployment worldwide. The device includes a complete
DOCSIS 1.1 MAC (including QoS) for broadband interactive
services and DAVIC 1.2/1.5 MAC.
The BCM7110 also includes a standard definition MPEG-2
video decoder and 2D/3D graphics subsystem. This allows for
the display of studio quality text/graphics and 3D effects. The
DVB/DCII transport of the device supports PVR. This support
includes time shifting on the program being viewed and
recording of another program, simultaneously.

A full PCM audio engine for mixing sounds into the main audio
stream is also on-chip. Outputs include left and right analog and
SPDIF.
The BCM7110 also contains a high-performance MIPS32 RISC
processor with 16 KB I cache and 16 KB D cache.
The BCM7110 includes a number of peripherals required for
next-generation set-top boxes, including USB host and device,
Ethernet, IDE controller for connection to disk drives, POD
interface for external conditional access, PCMCIA interface, and
a glueless IEEE 1394 interface. The BCM7110 also contains
support for the Broadcom V.90 softmodem.
On-board descrambling supports all major conditional access
systems and includes 3DES encryption/decryption for PVR.
The BCM7110 represents the most integrated, cost-effective set-
top box single-chip solution incorporating next-generation
requirements. It is built on the previous generation of Broadcom
silicon and software to offer a low risk and quick time-to-market
for interactive broadband set-top boxes.
