Broadcom Introduces Low Cost Digital Broadcast Satellite Chip

11/24/2004 - Broadcom Corporation (Nasdaq: BRCM), a leading provider of highly integrated semiconductor solutions enabling broadband communications, announced a highly integrated digital broadcast satellite (DBS) decoder chip that enables system manufacturers to lower their development costs, allowing them to provide more competitive and cost-effective DBS set-top boxes for receiving basic digital program services. The Broadcom® BCM7312 DBS system-on-a-chip integrates all of the required features and functionality of an entry-level DBS set-top box at significantly reduced costs by simplifying the set-top box design through reduced part counts. It also lowers power requirements and enables faster manufacturing times.

"With the BCM7312, we focused our engineering expertise on reducing the set-top box system cost for the U.S. market and international markets such as Europe, Korea, India and China," said Brian Sprague, Broadcom's Senior Director of Marketing, Set-top Box and Digital TV Products. "The BCM7312 is Broadcom's first product to address the high-volume entry-level DBS set-top box market and sets a new standard of technology achievement in integration and cost reduction."

The BCM7312 single-chip DBS set-top box MPEG-2 audio/video decoder is an advanced, highly integrated solution that reduces the number of chips on an entry-level set-top box from five to one. It is the first chip in its class to integrate a front-end RF tuner, which reduces the complexity of the design and offers significant cost and board space savings to manufacturers. The BCM7312 leverages Broadcom's expertise in developing technology for the DBS markets by incorporating all of Broadcom's field-proven set-top box technologies, such as a high-performance MIPS® processor, advanced graphics engine, dual USB 2.0 host controller and physical interfaces, and international standard-based audio and video technologies. The chip also includes the latest DBS conditional access security circuitry required by these target markets.

"DIRECTV communicated its direction to Broadcom earlier this year and Broadcom has shown its ability to react quickly to our requirements," said Roger Lambert, Vice President of Engineering, Set-top Boxes, at DIRECTV Inc. "We are impressed with Broadcom's integration capabilities and also with the anticipated cost reduction in this very competitive sector."

BCM7312 Product Details
The BCM7312 incorporates a fully integrated RF tuner, QPSK receiver, MPEG- 2 compliant audio and video decoders, and a MIPS32® CPU core operating at 266 MHz. The processor architecture also includes a MIPS16eTM Application Specific Extension for code compaction, which reduces system memory requirements and the size of the footprint. The integrated advanced 2-D graphics engine allows applications such as Internet browsers and electronic program guides to deliver studio-quality text and graphics. The on-chip video encoder supports NTSC, PAL and SECAM with optional support for Macrovision® 7.1. Additional on-chip functionality includes the video line drivers, voltage regulator, audio HiFi DACs and support for LNB control via the DiSEqC 2.0 controller.

The BCM7312 also includes direct access arrangement (DAA) interface module with direct connection to a Silicon Laboratories Inc. line-side device. This highly-integrated DAA solution can be used as the return channel modem required in many interactive STB and TV applications. This solution eliminates many bulky external components from the printed circuit board, and allows a low cost software solution. The integrated module precludes the need for the system-side DAA device, and thus further reduces the cost and space requirements for the modem. The Silicon Laboratories DAA is compatible with worldwide PTT standards to further minimize system costs for manufacturers.

Pricing and Availability
The BCM7312 along with the BCM97312 reference design are available now in sample quantities. The chip is priced at $11.99 each in quantities of 100,000.
