Next-Generation Si24xx Data ISOmodem® Family Offers Sophisticated
Voice Features for Security Systems, Home Automation and Point-of-Sale
Terminals
AUSTIN, Texas--(BUSINESS WIRE)--
Silicon
Laboratories Inc. (NASDAQ: SLAB), a leader in high-performance,
analog-intensive, mixed-signal ICs, today announced the next generation
of its widely used Si24xx ISOmodem family, offering advanced voice
features, lower power, reduced BOM costs and flexible interface options
for a wide range of data modem applications. The innovative Si24xx data
modem ICs address the need for voice and machine-to-machine (M2M)
communications for security and home automation systems, smart utility
meters, set-top boxes, point-of-sale (POS) terminals and many other
electronics systems that connect to the public switched telephone
network (PSTN).
The Si24xx ISOmodem family's voice feature set is more comprehensive and
offers better performance and audio fidelity than legacy data modem
solutions. When combined with Silicon Labs' popular Si3000 voice codec,
the Si24xx data modems support handset, speakerphone (full or
half-duplex), voice menu and answering machine implementations.
Developers can easily add telephony and voice functions to any embedded
system, without the need for the dedicated voice processing ICs or
host-based DSP software required by legacy approaches. The voice-capable
Si24xx ICs are ideal for any system with telephony functions ranging
from POS terminals and security systems to video phones and medical
monitoring equipment.
In addition to offering a complete suite of ITU-T "V-dot" data
communications, compression and error correction protocols, the ISOmodem
family supports specialized protocols used in security and POS
applications. Standard DTMF generation and detection and
user-programmable tone detection and generation give the Si24xx family
the flexibility to support non-standard custom protocols through host
software.
As part of Silicon Labs "green" solutions, the Si24xx ISOmodem family
offers the industry's lowest power consumption in both active and
standby modes. Operating from a single 3.3 V power supply, ISOmodem
chipsets draw very little power — 56 mW in normal operation (on-hook,
idle). Sleep and Wake-On-Ring (WOR) modes are available to reduce power
consumption to 0.3 mW and 15 mW, respectively. This capability allows a
system to appear to be "always on" while consuming very little power and
still responding to events on the telephone line.
Si24xx ISOmodem ICs are available in a tiny 5 mm x 7 mm QFN package,
resulting in the smallest total board area for embedded modem designs.
Developers can use a small, low-cost 32 kHz "watch" crystal instead of
the larger, more expensive crystal typically used in embedded modems.
The Si24xx devices also offer the option of using a serial peripheral
interface (SPI) in addition to UART and parallel interfaces, enabling
resource sharing among multiple peripherals.
"As the inventor of the leading silicon DAA architecture, Silicon Labs
continues to invest in embedded modem technology to help our customers
reduce power, component count and system cost," said Carlos Garcia, vice
president of Silicon Labs' Wireline products. "Our next-generation
Si24xx ISOmodem family gives developers the utmost in flexibility,
reliability, surge protection and advanced voice features for telephony
applications."
The Si24xx data modems leverage the patented architecture of the world's
most widely adopted silicon data access arrangement (DAA) solution.
Silicon Labs' global silicon DAAs deliver unmatched surge immunity
without additional BOM cost. One hardware design can support all speeds
and meet worldwide compliance requirements.
Pricing and Availability
Samples and production quantities of the Si24xx ISOmodem chipsets are
available now. Depending on the maximum data rate, system-side package
type and temperature range, ISOmodem/DAA chipset prices range from $6.44
to $11.43 in 10,000-unit quantities. Evaluation kits such as the
Si2494-A-FM18-EVB are available for $150 each. (All prices are in USD.)
