Default Industry's First 100% CMOS Satellite Radio Tuner

http://biz.yahoo.com/bw/031027/275206_1.html

Si2210 Reduces Board Space By 60% and Component Count By 70%

Silicon Laboratories Inc. today announced the Si2210 IC, the industry's first CMOS satellite radio tuner. The Si2210 leverages Silicon Laboratories' proven radio frequency (RF) technology to provide the best performing and most integrated Satellite Digital Audio Radio Services (SDARS) tuner on the market. Implemented in 100 percent CMOS, the Si2210 reduces the required board space by 60 percent and component count by 70 percent, significantly lowering the bill of materials for SDARS applications.

With the Si2210, Silicon Laboratories provides a complete RF/IF tuner, the core IC responsible for receiving radio signals for coast-to-coast, uninterrupted, satellite radio service. Silicon Laboratories, a pioneer in RF solutions in CMOS for cellular handsets, has been the leading supplier of integrated RF synthesizers since the launch of satellite radio. The company's patented RF technology is a key enabler in this rapidly growing consumer market, which is being driven by the adoption of major automotive manufacturers and is expected to add millions of subscribers.

"Silicon Laboratories' history of innovation in RF technology and the company's ability to meet the rigorous requirements of satellite radio has enabled more compact and cost-effective satellite radio solutions for the consumer," said Will Strauss, president of Forward Concepts, a market research firm. "This innovation is spurring the tenfold growth satellite radio is expecting over the next several years as consumers readily adopt this revolutionary technology."

"Silicon Laboratories' new tuner is a prime example of our ability to leverage extensive mixed-signal CMOS RF design expertise into new, growing markets where we can provide customers with innovative, high-performance solutions," said Dave Bresemann, vice president of Silicon Laboratories. "Our easy-to-use Si2210 provides customers with a flexible solution that meets both the stringent technical requirements of satellite radio and intense quality requirements of automakers."

Silicon Laboratories' new Si2210 tuner solution includes the Si2210 tuner and the Si2200 RF/IF synthesizer. The Si2200 integrates both RF and IF voltage-controlled oscillators, varactors and loop filters, eliminating the need for external VCO modules. This high level of integration results in ultra low phase noise and spurious noise while providing the industry's fastest settling time.

To simplify design, the Si2210 implements a highly integrated superheterodyne architecture, allowing SDARS radio manufacturers to significantly reduce cost while leveraging existing and future baseband technology platforms. The Si2210 also includes a standard SPI digital control interface that allows software programmability of satellite radio configurations and continuous monitoring of RF functions and antenna fault conditions.

Silicon Laboratories' satellite tuner product offering also includes the Si2211 for next generation baseband processors and the Si2212 for diversity applications. Using the Si2211, customers can further reduce the number of external components required by implementing a single SAW architecture, while the Si2212 provides the most advanced diversity antenna solution for the SDARS market.

Pricing and Availability

Silicon Laboratories offers the Si2210-GQ and Si2212-GQ tuners packaged in a thermally enhanced 64-pin TQFP or the Si2211-GQ tuner packaged in a 48-pin TQFP. Silicon Laboratories' tuner solutions also include the Si2200-GM RF/IF synthesizer packaged in a 28-pin QFN. Pricing begins at $8.85 in quantities of 10,000. Complete evaluation boards are available now for $150.

Will Siri or XM license this?

Interesting they didn't mention any design wins yet. I suppose who has selected it to use is probably a secret for now. I would guess both XM and Sirius would use this so long as it provides a cost reduction and equivalent or better performance.

1) "is expected to add millions of subscribers."

2) "This innovation is spurring the tenfold growth satellite radio is expecting over the next several years as consumers readily adopt this revolutionary technology."

I'd say it was a good article......

This should also mean that the devices will no longer be as hot as they are now.. I know I have read a few people commenting on how hot the H2A gets.

I hope this whole thing is digital... would be nice for sound quality too.

This chip is for the RF receiver front end which doesn't consume lot's of power and therefore doesn't generate lot's of heat even in the current version. Most of the heat in the H2A and AudioVox is from the baseband signal processing (digital chipset) and the display backlighting. For heat reductions we will need Gen3 chipset which will probably reduce power consumption by 50%. Look for these chips next year.

Hopefully it will be substancially smaller and run cooloer. This will at last allow SIRIUS to start building smaller units. Walkman, I am not sure about the fesability of that. I certainly have no interest in one, but that is just me. You will always require line of site, which means an antenna will have to have access to the ski. Have the walkman unit on your side and an antenna hat on your head? Forget walking through the mall or hiking or jogging in heavily wooded areas (except in areas with repeaters). Kind of kills the useability of a walkman type unit. I suspect at some point there will be one, but I think it will be later rather than sooner.

You guys forget i have xm on my wheelchair and i do go in buildings as well as ride the bus daily and listen to it indoors at home, malls, multistory buildings and other parts of a college for classrooms as well as offices. I may of sold xm to a prof who cant get radio in his windowless office, but my xm worked fine in there.

I find XM worked eevrywhere except near elevelators. In buildings with or without windows. SOmetimes it may cut out in a hallway but work in a bathroom. Its really strange where it does and doesnt work.

I assume the antenna will be made into the band of the headphones, top of the pocket radio unit if not a arm band. Maybe they have something we know nothing about like dual wips on each ear piece?

Jeff, how many repeaters does XM have in your area? Because unless SIRIUS has some there too, you will NEVER be able to use it in the same manner that you do XM. XM has an advantage on this type setup due to its huge repeater network. SIRIUS relies mainly on line of site. Which is my point as to why them getting a walkman type device out isn't much of a priority.

Once Sirius becomes profitable, I suspect they will add repeaters in more populated areas as a way to get better indoor coverage and expand the market even further.

That would probably be a very wise move.

The annual report lists 98 repeaters in 61 markets. That's up from 92 in 50 markets a year ago. It also states that more may be added to ensure superior coverage. Earlier this year they said 50 would be added to fill gaps and to assist with Hertz operations.

We're still a ways off from XM's 1100+ repeaters. Just think what 100 more would do for Sirius with the already highly robust 3-sat constellation.

The biggest factor slowing buildout is zoning regulations. From the time they identify a dead-zone to the time a permit can be approved, tower space located and constructed it can be a year or more.
