Advanced DVB-S2 Receiver Chip First to Integrate Dual Tuners and Demodulators, Resulting in Significant Reductions in System Board Space, Power and Cost
DVB-S2 is an advanced satellite transmission specification that expands and improves upon the earlier DVB-S standard that is deployed in integrated receiver/decoder (IRD) solutions all over the world. The new standard offers improved modulation efficiency over the DVB-S standard. In addition, when combined with new video compression technologies such as H.264 (MPEG-4 Part 10/AVC) for high-definition television broadcast and interactive TV services, DVB-S2 further improves bandwidth efficiency for accommodating additional content and high quality programming for consumers.
Broadcom is the first company to develop a DVB-S2 satellite receiver chip that integrates the demodulators and tuners into a single-chip design. Other silicon solutions require separate DVB-S2 tuners and demodulators, which significantly increase the number of components on the receiver design and result in increased bill of material costs as well as power consumption. Announced today is Broadcom's new BCM4501 DVB-S2 receiver chip that integrates two tuners and two demodulators, reducing the number of components on a dual DVB-S2 receiver design from four chips to one and reducing power consumption by more than 40% over current multi-chip devices. These reductions significantly lower the system bill-of-material costs and reduce the complexity of dual tuner DVB-S2 satellite receiver designs.
"We are pleased to provide this highly integrated satellite front-end solution to customers today especially when advanced satellite products are being rolled out in volume production," said Brian Sprague, Senior Director of Marketing for Broadcom's Set-Top Box Line of Business. "By providing a single-chip design that includes dual tuners and demodulators, Broadcom is once again enabling satellite equipment manufacturers to reduce system board space, power and cost for their high definition set-top box platforms."
"With a growing number of HDTV channels to be delivered by satellite pay-TV providers in 2006, those pay-TV providers are looking to the higher capacity enabled by DVB-S2 for more efficient HD channel delivery," said Michelle Abraham, Principal Analyst at InStat. "In 2009, we expect satellite set-top boxes with next-generation advanced modulation technologies to account for 30% of the worldwide satellite set-top box unit shipments."
The BCM4501 DVB-S2 receiver provides a seamless interface to Broadcom's BCM7400, BCM7401 and BCM7402 AVC/MPEG-2/VC-1 single-chip solutions as well as to the BCM7038/BCM7411 decoder chipset, offering solutions for set-top boxes that can simultaneously support one or two high definition (HD) AVC broadcast channels. Two HD AVC channels enable end users to watch an HD AVC program while recording another or to record multiple programs at the same time. The BCM4501, when combined with the BCM7400 (also announced today), is the industry's first two-chip solution for dual HD-AVC decode, dual HDTV or dual HD picture-in-picture set-top box configurations.
BCM4501 Product Information
The BCM4501 is a dual DVB-S2 satellite receiver chip that integrates two CMOS tuners and two advanced demodulators supporting DVB-S2, DVB-S and DIRECTV(R) broadcast applications. The new receiver chip can support all high volume, advanced modulation DVB-S2 and DIRECTV network deployments while maintaining backward compatibility with DVB-S and DigiCipher II satellite networks. An Integrated Frequency Translation Module transceiver/communication link enables the BCM4501 to cost-effectively support multiple low noise block (LNB) configurations over a single coax cable connection that eases home installations while reducing cable requirements in the home.
Pricing and Availability
The BCM4501 DVB-S2 satellite receiver chip is available today and is priced at $25 in quantities of 1,000 units or more. The BCM4501 is packaged in a 208-pin MQFP.
