• Manufacturer Part Number: bcm7003
• Description: Sd Cable Interactive Receiver With Usb Dvr
• Manufacturer: Broadcom Corp.

The BCM7003 is a highly integrated low-power solution combining the
functionality of a complete Cable Tuner-to-NTSC/PAL converter on a
single chip. It provides DVB-C QAM signal reception, with
functionality targeted at SD Cable Interactive and USB PVR
applications.
This all-silicon solution minimizes part count and provides ease of
manufacturing. The comprehensive integration of the Cable Tuner,
ADCs, and DACs simplifies system design and cost and has direct
interfaces to all other system components, including serial Flash (SPI),
tuner (I
The BCM7003 includes USB connectivity. In conjunction with
Broadcom’s DVR software, the BCM7003 enables low-cost DVR
solutions for emerging markets. It also has a 10/100 Ethernet MAC for
connectivity, enabling two-way services such as VoD, browsers, and
interactive applications.
The BCM7003 supports advanced security including Nagra, NDS,
Irdeto, Latense, and Conax. The BCM7003 has a toolkit of security
components to meet a wide range of conditional access requirements,

BCM7003 will be factory OTP-programmed with its unique private
password. JTAG and Broadband Studio ports may be OTP-locked at the
stage of product factory test. A single high-fidelity fixed 54 MHz crystal
clock is used to clock in the entire SoC.
The BCM7003 has an MPEG-2 Digital Video Broadcasting (DVB)-
compliant transport processor with advanced section-filtering capability,
MPEG-2 (MP@ML profile) video decoder, a Dolby AC3/MPEG-2
audio decoder, a pair of analog audio outputs (L-R), and a single NTSC/
PAL video encoder with analog output.
The BCM7003 incorporates a complete MIPS32
subsystem, including caches with bridging-to-memory and a local bus,
where integrated peripherals are attached. Integrated peripherals include
universal asynchronous receiver/transmitters (UART), counter/timers,
general-purpose input/output (GPIO), IR transmit (TX)/receive (RX),
Broadcom Serial Control (BSC), and Serial Peripheral Interface (SPI)
controllers.
