Si2185 Receiver IC Integrates Digital/Analog TV Tuner and
Demodulators to Simplify TV and Set-Top Box Designs
AUSTIN, Texas--(BUSINESS WIRE)--
Silicon
Laboratories Inc. (NASDAQ: SLAB), a leader in high-performance,
analog-intensive, mixed-signal ICs, today introduced the industry's
first single-chip hybrid TV receiver family designed to simplify the
design of TVs, set-top boxes (STBs), Blu-ray recorders and PC
accessories. The new receiver family includes the Si2185 hybrid
receiver, which combines a digital/analog TV tuner, a multi-standard
analog demodulator, and DVB-T and DVB-C demodulators into a fully
integrated, monolithic solution. The receiver family also includes the
Si2115/13/11 digital-only receivers designed for DVB-T and DVB-C digital
STBs offering terrestrial and cable reception.
The new Si2185/15/13/11 receiver family enables TV and STB developers to
eliminate numerous external components such as surface acoustical wave
(SAW) filters, tracking filter inductors, wirewound inductors and
low-noise amplifiers (LNAs), thereby simplifying their designs and
reducing BOM cost. The receiver family's unprecedented single-chip
integration can enable a total system savings of up to 75 percent
compared to more complex two-chip solutions.
Silicon Labs' single-chip TV receiver architecture provides a fully
optimized, integrated signal path from RF antenna input to demodulated
digital or analog baseband output, enabling superior RF performance. In
addition, the single-chip design eliminates the sensitive
intermediate-frequency PCB traces used to connect a tuner to a separate
demodulator, reducing the likelihood of system noise interference and
degraded performance.
The superior sensitivity of Silicon Labs' TV receivers (with a very low
4 dB noise figure) makes it easier for TVs to receive weak RF signals,
allowing viewers to receive more channels. The receivers also offer
excellent front-end linearity and channel selectivity, resulting in
better reception in crowded spectrum areas. Strong blocking performance
is especially critical in urban settings where many undesired blocking
channels can reduce the number of channels received.
"Silicon Labs' new TV receiver family represents a significant technical
achievement in the broadcast video industry," said James Stansberry,
general manager of Silicon Labs' broadcast video products. "We've broken
new ground in RF integration by demonstrating the ability to combine a
silicon TV tuner with analog and digital TV demodulators into a
single-chip receiver solution that enhances system performance and
simplifies TV and STB designs."
To ease application development, the Si2185/15/13/11 receiver family is
supported by a unified software application programming interface (API)
that encompasses both tuner and demodulator functions. This unified API
simplifies software design compared to competing two-chip solutions,
which require separate APIs for the tuner and demodulator. In addition,
all members of Silicon Labs' receiver family are pin and software
compatible, which helps reduce the cost of developing TV and STB
products for multiple markets.
Pricing and Availability
Samples and production quantities of the Si2185/15/13/11 TV receivers
are available now. The Si2185 receiver is priced at $3.12 (USD) in
10,000-unit quantities. Pricing for the Si2115/13/11 receivers begins at
$2.55 (USD) in 10,000-unit quantities. The Si2185-A-EVB and the
Si2115-A-EVB, both priced at $495 (USD MSRP), provide comprehensive
evaluation platforms for hybrid digital/analog TV platforms and digital
DVB-T and DVB-C TV platforms, respectively.
