• Manufacturer Part Number: bcm7004
• Description: Sd Cable Basic Receiver
• Manufacturer: Broadcom Corp.

The BCM7004 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 zapper and basic applications.
This all-silicon solution minimizes part count and provides ease of
manufacturing. The comprehensive integration of the 866 MHz 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 BCM7004 supports advanced security including Nagra, NDS,
Irdeto, Latens, and Conax. The BCM7004 has a toolkit of security
components to meet a wide range of conditional access requirements,
including ISO 7816 SmartCard interface, DVB-CSA, 3DES key
management, and bootloader ROM. Each BCM7004 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 BCM7004 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 BCM7004 incorporates a complete MIPS32
subsystem, including caches with bridging-to-memory and a local bus,
where integrated peripherals can be 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.
